Even so its fair to say that this benchmark shows exactly how poor intel performance on linux/ubuntu is so maybe this might do some good to kick the xorgintel driver team into making some better drivers.

The thing that gets my goat is that this benchmark and the comments that go with it suggest that linux has poor graphics performance in general which simply isnt true - animation studios and people doing serious 3D graphics work use linux, mostly with NVidia graphics sinec their support is way better then intel and amd.Edited 2009-05-13 01:31 UTC Wed, 13 May 2009 01:29:00 GMT donotreply@osnews.com (ideasman42) Comments Hardware was the same http://www.osnews.com/thread?363209 http://www.osnews.com/thread?363209 The hardware used was the same Mac Mini.

There are probably real-world performance differences with 3D graphics on Intel, but in my normal use, the Air was significantly less responsive than my regular computer; in fact it wasn't much faster than my netbook.

Embarrassing. Wed, 13 May 2009 02:11:00 GMT donotreply@osnews.com (3rdalbum) Comments RE: intel on linux isnt a great comparison http://www.osnews.com/thread?363220 http://www.osnews.com/thread?363220 That might be true, but I have yet to have seen any graphics card which runs faster on Ubuntu (even the Nvidia ones in the past at least seemed to be quite consistently slower on linux).

There are two problems here:
1) Having a kernel that forces people to provide open source drivers. Whilst linus tolerates closed source drivers, its a risk creating them. And companies aren't going to pour all their optimisations into open drivers which any other company can just steal the optimisations. Otherwise its like handing over money to the competition.

There is no good justification for this. If Open source is that great, then such drivers will succeed regardless.


2) Ubuntu doesn't develop linux, it just grabs a bunch of packages which other distro's have worked on. Canonical seems to only concentrate on their own projects.

Whilst the foundation of Ubuntu is shaky, Canonical is off spreading their resources further and starting other projects like the netbook remix, which has a shaking foundation too because barely any drivers on either are complete. And I have seen NO evidence of Ubuntu trying to collaborate with other companies either, to determine their needs. Everything seems based on assumptions.


3) The community. I've learnt from the Ubuntu brainstorm community that frankly, the most vocal Linux users are idiots. That's the biggest problem. I've argued with Linux users who believed that time shouldn't be wasted on wysiwyg editors because grandma should learn mockup languages / CSS instead for her site. And I've argued against many users who were totally convinced that DEB's/RPM's are more secure then shell scripts. Ubuntu's vocal population I think has turned too much into politicians who care more about spreading OSS then aiming to make the best software.

Compare QT/Cocoa to GTK for instance. GTK obviously gets dominated in general cases, yet, plenty of people seem to be on a crusade against C++. Its rediculous.

And because of the community, the end result is that Linux is still too risky to develop for.


I wouldn't blame the xorgintel team for this. If the community gave up their holy war and started once again writing the best software they can, because they want to (not because of politics). You'd end up with an MIT kernel which was completely open in all ways, and software which was developed with users in mind.

So, Mac OS X wins a few tests, good or bad, but why are people making excuses for Linux here? Wasn't it fair in the past that the graphics drivers weren't the best or that Canonical didn't optimise anything when Linux was winning?

It's not exactly that any of this matters since it's not going to change anyone's mind really. I'd be more interested in seeing how FreeBSD performs against Mac OS X since they share bits and pieces quite often.

Assumes that only companies can write optimised software. Not a valid assumption at all. The one and only advantage that companies have in writing software is that companies have access to secret information held by ... companies.

Clearly not ready yet, but definitely on its way. Enjoy (when ready).

So ATI have released documentation (specifications) of their chips to open source programmers, open source programmers are busily writing an open-source driver for Linux for ATI chips, so that ATI chips will soon become the most powerful graphics chips available with a decent (non-binary-blob) 3D driver for Linux, which will no doubt be supported directly within the kernel, and hence Linux buying public will tend to buy ATI chips.

There is a lot of misinformation being spread right now about Linux having only a small market share. They are actually talking ONLY about the desktop market.

If we are talking about the entire market wherein the devices you mentioned (3d graphics, wireless, acpi) are used, Linux would have a very decent market share of that entire market. Perhaps 20% or so.

I too saw those marks and interesting how you ignore the follow up which explained why some of them were the result of the default configuration as with the case of the MySQL benchmark. It has nothing to do with micro versus monolithic versus hybrid versus chocolate bar with sprinkles on top.

Mac OS X was designed first and foremost as highly responsive desktop operating system. There are sacrifices when you focus on latency and responsiveness over throughput; and yes, when it comes to responsiveness, Linux doesn't even come close to Mac OS X.

It sounds more like you need to upgrade your ram than get a kernel optimized for desktop use. It's not exactly a secret that current mainstream Linux distributions are less memory efficient than XP

I find OS X to be downright viscous -- as though there is perceivable latency between the input devices and the screen.

Hmmm lets see what does Ubuntu develop? How about notify-osd, the new growl-like notification system which is controversial but very pretty? How about usplash, the userspace bootsplash (soon to be replaced however). How about upstart, the new event based init replacement good enough for Fedora AND Debian to both adopt in the default installs? Granted, it is (IMO) crap, but how about the python ORM storm? Do you even know what an ORM is used for?

If you get the "deb/rpm" from a reputable source like oh your distribution's package repository it will be GPG signed. Yes my friend, that is more secure than a shell script.

Woah, hang on - it has nothing to do with efficiency of memory; this was running ArchLinux whose total memory foot print was less than Windows XP - so it has nothing to do with the memory consumed. What it has to do with is the algorithms that are used to balance processes/threads to ensure that the end user gets a responsive system.

Pardon? nothing is slow to me; maybe it takes a second to load up the window to display the contents of the drive, or it takes a couple of seconds for an application to load by clicking on the dock but what I am talking about is smoothness when running 3-4-5-6 applications at the same time.

As stated, Ubuntu was using v1.4, while OSX was only using 1.2. Most games, especially ones as optimized as ioquake3 (the engine that drives Urban Terror), will use different render paths for different versions of OpenGL. Most likely, ioquake3 saw OSX was using an older version and turned off some of the features. In Ubuntu, the newer version triggered the newer features, which on Intel graphics is done via software since the Intel GPU hardly does anything in hardware.

So the difference wasn't so much optimized Apple drivers vs unoptimized linux drivers as it was old rendering path with more hardware acceleration vs newer rendering path using software. I'd bet that if they redid the test with UT set to the lowest values for the rendering quality, both would show nearly the same FPS values.

Out of curiosity, have you tried switching to desktop-optimised kernel and seeing what happens? I would be hesitant to declare that the scheduler is the major factor in performance differences between two operating systems, but very interested to see what difference it makes.

As for OS X, my understanding is that low latency means a negligible delay between user input and the output appearing, which is exactly what I haven't noticed while using it.Edited 2009-05-13 06:39 UTC Wed, 13 May 2009 06:38:00 GMT donotreply@osnews.com (6c1452) Comments RE: Problem with Urban Terror test http://www.osnews.com/thread?363289 http://www.osnews.com/thread?363289 No, I think the main issue is that they are benchmarking an irrelevant game which barely no one plays.

Funny, as repsonsiveness is one of my biggest gripes about Mac OS X. I've used the most powerful Macs you can imagine, and even those that herald the coming of the starborn ones (to paraphrase Yahtzee) have noticeable delay when launching applications or interacting with them (buttons, menus, etc.).

This is absolutely intolerable. Mac OS X is smooth, yes, but not when it comes to responsiveness.

I am assuming both Crafty's were compiled with the same compiler. If not then one has also to take into account that there is a large difference in performance among compilers.

I too saw those marks and interesting how you ignore the follow up which explained why some of them were the result of the default configuration as with the case of the MySQL benchmark. It has nothing to do with micro versus monolithic versus hybrid versus chocolate bar with sprinkles on top.

Mac OS X was designed first and foremost as highly responsive desktop operating system. There are sacrifices when you focus on latency and responsiveness over throughput; and yes, when it comes to responsiveness, Linux doesn't even come close to Mac OS X. If I counted the number of times my netbook came bogged down and poorly responsive with a couple of applications open versus Windows on the same machine - I'd be here all day.


Until 10.4.x, Mac OS X was never interactively responsive for me. I know that was the intention but it never happened, even on dual processor machines. My Ubuntu machine feels better but even that has some odd performance foibles.

It sounds more like you need to upgrade your ram than get a kernel optimized for desktop use. It's not exactly a secret that current mainstream Linux distributions are less memory efficient than XP

I find OS X to be downright viscous -- as though there is perceivable latency between the input devices and the screen. It's possible I'm just imagining things because of the way desktop effects slow down some other actions, but that's how it feels.


I haven't seen that kind of performance since version 10.4.x, even when it's short on available real memory, though I've had stuttering from the virtual memory system when an application tries to implement its own system.

The graphics card has a lot to do with it, though, since OpenGL is used in many places. The early Intel-based machines with the early Intel graphics chipset lagged a lot but then, they weren't able to access 226 MB of shared RAM in Mac OS X the way that they could under Windows.

Under low-load (means less than 100%) conditions Linux is a bit less responsive than Windows. Under full load Linux is by far more responsive than Windows (at least XP).

I had two machines with 4 cores each, the Linux machine even being slightly slower (2.8 GHz vs. 3.0 GHz).
I ran a finite element calculation on each using all 4 cores, both machines needed 1.5 GB RAM for this calculation and had plenty of RAM available for other stuff. CPU utilisation was 100% at both machines, both processes ran with standard process priority. None of the machines had to swap.

On the WinXP machine it was not possible to do anything productive during number crunching. On the slightly slower Linux machine working was slightly less responsive than without load, but still good. And by the way, my work included software like Salome, GIMP and OpenOffice where responsiveness definitely IS an issue.

When looking into desktop performance, the high-load scenario is not the typical one, on the other hand if you sometimes DO saturate your processor, having still good response is definitely a plus.

I think that everybody needs to decide on his own which behaviour is most satisfying to him. Wed, 13 May 2009 14:28:00 GMT donotreply@osnews.com (gustl) Comments RE[3]: intel on linux isnt a great comparison http://www.osnews.com/thread?363432 http://www.osnews.com/thread?363432
This whole issue has nothing to do with having an open source kernel or gtk vs. cocoa or whatever.

It has everything to do with market share. Linux will get great desktop hardware support (3d graphics, wireless, acpi) when it has decent desktop market share.


The problem is it seems it is never going to happen until Linux gets its act together. I have heard : this is the year of the desktop Linux for the last 10 years.

For me, I couldn't care less about the speed of one application all by its lonesome self; what I am talking about is a system under a reasonable load and getting some decent responsiveness from it.


Funny, as repsonsiveness is one of my biggest gripes about Mac OS X. I've used the most powerful Macs you can imagine, and even those that herald the coming of the starborn ones (to paraphrase Yahtzee) have noticeable delay when launching applications or interacting with them (buttons, menus, etc.).

This is absolutely intolerable. Mac OS X is smooth, yes, but not when it comes to responsiveness.

Before I get the usual group of Mac fans on my bum: the above does not imply, in any way, that Windows does this any better. "

I believe you are confusing things. Responsiveness has nothing to do with launching Apps. It has to do with how the system take care of your requests and events.

A slow application, does not mean the system is not responsive enough, or a slow launching.

However, if the menu bar that does not appear when pressed it is a responsiveness issue. That is particularly true in Applications written in Java, but they are unresponsive in every platform, even Windows.

Windows, and Linux are very fast, but when you have your processors at top capacity, both systems get very unresponsive, especially Windows. Mac OS X, usually keeps receiving and behaving properly under the same circumstances.

Exactly.

So when I click a launcher, the app needs to be there instantly to receive brownie points. When I press the close button, it needs to disappear instantly for brownie points. When I press a menu button, the menu should appear instantly. Etc. Mac OS X simply does not perform optimal when it comes to responsiveness.

I'm from a BeOS world, and anything less than instant responses is evil and bad and should cause people to be fired.

Mac OS X totally sucks in this department, even on very powerful machines. Windows XP and esp. vista sucked balls here too, but Windows 7 seems to have nailed it pretty good (still not good enough though). Sure, it needs tricks like SuperFetch and such to get there, but I'd rather have tricks getting me there than not getting there at all.

On 7, all the applications I use appear instantly - Chrome, Office, Miranda, you name it.

Expect the decent, open-source, 3D drvier for ATI chips to follow within a month or so.


Intel had open specs and open drivers for far longer than ATI, the chip is simpler AND they actually have paid developers for the xorg driver. The intel driver is probably the best maintained driver for xorg right now.

The result?

The benchmark here clearly shows that the result is not what you would expect, the performance is awful. Comparing my hp box at work, the graphics performance are actually better in vista than linux with the xorg-intel driver, even after tuning the driver parameter for migration heuristics (which did a HUGE difference).

Compare this to the nvidia binary blob, which gives me the opposite result on another box. ATI is in an unusable state at the moment (I'm not taking sides with any graphic vendor, that's just a fact).

It is true. Mac OS X is not as responsive as it should on the user interface department.


I'm from a BeOS world, and anything less than instant responses is evil and bad and should cause people to be fired.


That's not true. BeOS was very responsive, I used it, but it was not that responsive, especially considering how old the graphic interface in BeOS was. BeOS was not as responsive as Mac OS 9, for example. Mac OS 9 has its problems, but responsiveness was not. All the time the user was first (Except when the system hanged itself).

Preemptive operating systems, are not as responsive as cooperative multitasking systems, for obvious reasons, but you gain robustness.

BeOS display technology, was not either even 1/10 of the sophistication Mac OS X or Vista has. BeOS was pixel related, very similar to what Mac OS 9 was and Windows XP is. Everything was a bitmap.

Mac OS X, in contrast, is PDF-vector related, heavy transparent (everything has alpha channel, even if it is not used), double buffered. (It has to be slow, because everything is written on the screen twice), heavy anti-aliasing, etc. How do you think those animations are made? Vista is similar to Mac OS X in that respect.

Seriously. Have you ever USED Mac OS 9 and BeOS?


HA HA HA! Yes I used both of them.

BeOS was very fast. No doubt about it, especially because it was a real multitasking system. But we are talking here about responsiveness, and there are many things to consider. Let me explain.

For example, multitasking responsiveness... In that regard, BeOS was amazingly fast. The king of its time... And it might be the king even by today standards.

But when you say interface responsiveness on one application only... Like hitting a button, or pulling a menu... Sorry, Mac OS 9 was faster. I did many tests at the time. The answer is simple: Mac OS 9 gave all the processor to the front most app, while all other background processes were desperately craving for attention. UI was usually coded on the same thread as the interface, so when the user was using the front most App the whole processor was just waiting for the user.

If you tried to do something "heavy" in the background, like CD burning, or printing, it was a disaster for the background process. Usually you lost CDs (buffer under run), or spend hours printing a page. But the front most App buttons were responsive. Was it good to be so responsive in the User Interface department? Maybe not. It has to do a lot with how you want the system to be perceived, but that is the reason cooperative multitasking was used on personal systems at the time: Windows and Mac. Preemptive systems like BeOS, while more robust, did not "feel" fast. BeOS shared the processor with all the background processes trying to give them a fair portion of time to each one. Mac OS up to 9 did not.

Windows has a similar approach even these days, that's why Windows is so bad on all multitasking tests, comparing it to Linux or any UNIX. And that's way so many users say Windows feel faster than Mac OS X or Linux, or any other UNIX.

See this, for example:

http://mobile.osnews.com/story.php/19769/Ubuntu-8.04-vs.-Windows-XP...

Of course, if you used BeOS in an Athlon 1 GHz you would not see the difference, just as many people swear Vista is fast on their 4 GHz Quad Core machines... I remember I conducted my tests on a PowerPC 180-225Mhz, 64 MB RAM. Many Mac users at the time noticed BeOS speed, especially rendering things, but many said user interface felt faster on the Mac. Again, the same word Windows people use today: "feel faster". Sat, 16 May 2009 04:44:00 GMT donotreply@osnews.com (DavidSan) Comments
