This reminds me of the quote I read a while ago on LWN from Linus .

Saying something along the line of : If you want something implemented in Linux just post the benchmark showing that Solaris is better at it

A link to what these tests kind of do :

If nothing else it would eliminate the "it's beta software" comments that will probably appear as people read and interpret the results.

Or, they could benchmark Fedora Core against a recent Solaris Express build and try to level the playing field.

More information on how the system was setup with each OS and compile options would be helpful as well.

In the benchmarks from the previous Solaris/Windows test, Solaris slammed WinXP in just about every category, and in this set of benchmarks, it looks like Linux is a real competitor. I'm sure they're out there, but I'd like to see the same set of benchmarks for Linux vs Winxp and Vista.

Overall it looks like Solaris is the better performer, but I wish more data was provided to explain WHY... as in what are the code differences between the two that would account for the differences.

The other score I found interesting was the bzip test. Would it have anything to do with disk performance in that case? How does Geekbench generate the scores, are they all time-based? Yeah, I could go and read the geekbench docs I reckon... but a quick blurb about this stuff would have been extra nice.

The strange thing is, even though we do development work on Solaris, our systems group won't allow us to use the Sun development tools at this point. Weird, huh?

They've been using gcc here since well before Sun's tools were free, so that explains part of it...

All these comparisons always test the wrong things. With the almost hatred between OS camps, it's *amazing* to me that there are VERY few decent comparisons between the OSs in real-world tasks.

Somebody send me a Sun box that can run Solaris and Linux, and I'll put it through some REAL paces. You know, webserving, database work, etc. I can't believe people have yet to do respectable benchmarking, it's not exactly rocket science.

It as far as I can tell, the GeekBench focuses on integer/floating point/memory bandwidth tests which do not depend very much on operating system structure and depend a lot on compiler quality. If the GeekBench was benchmarking I/O performance, then it would be a more appropriate measure of operating system performance.

Why would the raw integer/floating point performance be different under Windows vs. Solaris vs. Linux? What part of the operating system affects this? Fri, 27 Oct 2006 19:55:00 GMT donotreply@osnews.com (spacebubble) Comments http://www.osnews.com/thread?176110 http://www.osnews.com/thread?176110 Geekbench uses a number of different benchmarks to measure system performance

Integer benchmarks measure integer performance by performing a variety of processor-intensive tasks that make heavy use of integer operations

Floating point benchmarks measure floating point performance by performing a variety of processor-intensive tasks that make heavy use of floating-point operations.

Memory benchmarks measure both memory hardware and memory library performance

Stream benchmarks measure both floating point performance and sustained memory bandwidth.

Indeed, and if you look at all the geekbench benchmarks it's clear that its propose is to compare "systems", aka "different machines with different hardware". The benchmarks are compiler-biased, which is great to compare different systems running the same OS, but not two different OSes running diffrent compilers. the one remotely interesting benchmark seems to be the "memory benchmarks", which measure stdlib performance (aka, libc)

I'm amazed at how good is the sun compiler in many cases, BTW.Edited 2006-10-27 19:59 Fri, 27 Oct 2006 19:56:00 GMT donotreply@osnews.com (diegocg) Comments http://www.osnews.com/thread?176117 http://www.osnews.com/thread?176117 Even if it is primarily depending on the compiler, I think that this is still very appropriate. As is the benchmark will reflect the relative performance of the common configurations of the 2 operating environments. When people install Solaris, chances are they'll be using the SUN compilers. When people install Linux, chances are, they'll be using GCC. Sure you can use GCC on Solaris and Sun Studio on Linux, but I would venture to say that most people don't.

Again, I'll make it clear. Heck, if anybody in Hawaii has a Sun box sitting around, I'll gladly travel to your location and give it a go. Or, you're welcome to come by my data center and set it up in there.

Well, most benchmarks are useless and don't really represent the real world. You should build a real world application that makes a good and fair use of OS facilities to test performance. Even then, what works best for you would not work well for others. So it's rather poinless. Look, most business are using Windows as their platform with all its problems of performance and security.

You may think linux super in desktop area though only has .4% market share. But in server area, linux is just a toy box. Proprietary unix like Solaris, SGI, HPUX, AIX, XENIX, etc, and FreeBSD were out there for a long time. Recently Solaris goes open source, so people can compare it with linux.

I would say it's about 4-5%, not .4%

"But in server area, linux is just a toy box"

Big 500 fortunes companies like the toy for sure.

" Proprietary unix like Solaris, SGI, HPUX, AIX, XENIX, etc, and FreeBSD were out there for a long time"

Solaris? Then why Sun commits its resources to Linux?
SGI? It's almost broken.
HPUX? Does anyone use it today?
AIX? IBM has commited resources to Linux. Maintaining AIX source costs money.
XENIX? Come on, are you joking me? What's next? DOS?
FreeBSD: I respect it, but its licensing scheme is problematic. Linux succeded because of the GPL. Not a technical merit.

Wow, just wow.

Sun commits is resources to Linux to give its customers a choice about the OS they wish to run. Their hardware is certified to run Solaris, Linux, and Windows.

NASA seems to have a lot of success with SGI as do other gov't. labs

HP-UX: You should look at job postings for system admins sometime, I see a ton of HP-UX work out there as well as AIX.

AIX: So what if it costs IBM money, you don't think that working on Linux is free for IBM?

You use the right tool for the right job. If a company has lots good experiences with commercial UNIX systems and can get them for a good TCO, why switch?

However, I suspect the impact of the OS is much smaller than the compiler; given that the test has two independent variables it's impossible to tell for sure.

So I agree with you that Solaris is a real competitor, but I think the underdog is Linux, with less time to mature and (theoretically) less centralized corporate involvement.

If this graph http://upload.wikimedia.org/wikipedia/en/0/0e/Unix.svg is to be believed, then Linux pre-dates Solaris 2.x (not only x86). I think the earliest Solaris x86 was release for version 2.4 in 1994.

I believe the first release of Solaris x86 was
Solaris x86 2.1 in May of 93 and Linux 1.0 was
March 94. But those are release versions. There
was all kinds of development activitey before that.
Interesting the chart didn't include some of the
other versions of x86 Unix back than such as
Interactive, Microport, Wyse, Esix and if I remember
correct Dell. But than again you can through
a lot of money at a software project it doesn't
mean your going to get the "best of breed". I'd
say back than Solaris x86 and/or the other versions
of x86 unicies where more complete for commercial
purposes. The hardware for those platforms where
more of a pain.

This makes the Linux kernel all the more impressive when you see results like these, IMO.

http://www.stdlib.net/~colmmacc/2006/04/13/more-ubuntu-on-t2000/

Although the kernel may not tend to benefit so much from compiler optimisations as things like these benchmarks, it wouldn't be unlikely to get at least another 5% or so on the above test.
