"A lot of people has been asking me about some performance comparison for the vector graphics framework we have. Rendering polygons, especially when we're dealing with stroke, tends to be the most expensive rendering operation performed in vector graphics. I constructed a little test, which tests raw polygon rendering power of Qt and Cairo. For the test I used the latest Qt main branch, and the master branch from Cairo's Git repository."
"Oh sure, the following tests aren't as scientific as putting all the browsers in a ring and seeing which one is left standing after the fight, but it's close." More here.
The PPCNUX-Team ran a benchmark on various Macs and operating systems, including the new MacPro. "When I tested the iMac Core Duo back in May the results were far better than I expected. That given, the Core2 disappoints me. Yes, it is faster than the original CoreDuo; but with all its announced enhancements I expected more. Its not the major leap ahead I expected."
Any computer gaming enthusiast has probably seen his fair share of gaming benchmarks in the past, but how accurate are benchmarks determined by recorded playbacks? ExtremeTech's Jason Cross built both Intel and AMD-based systems and recorded performance based on actual gameplay of six popular gaming titles, using FRAPS to measure performance. High-end systems from Intel and AMD, in this case the Core 2 Duo and Athlon 64 X2 5000+, delivered superb performance, although Intel's newest architecture takes the cake across the board.
" can easily enjoy the best of both the Mac and Windows XP worlds on a single system--as long as that system is an Intel Mac. Apple's own Boot Camp Public Beta allows you to install Windows XP SP2 onto an Intel Mac, giving you a dual-boot system. Parallels takes a slightly different approach with its Parallels Desktop for Mac, a virtual machine application. CNET Labs ran a few of its home-brewed benchmarks on a MacBook Pro with the Mac OS, Boot Camp, and Parallels Desktop to see how application performance stacks up between the three."
"Since the second computer was built, users have compared the performance of different computers. Performance matters. Sometimes, a performance difference is just a question of whether a job will be done sooner or later; in other cases, a performance difference might prevent a job from being done at all. Measuring performance of a particular task is not too daunting, but developing a prediction of how quickly other tasks will run can be nigh impossible. A benchmark is a task designed such that a measure of performance on this particular task will be a good proxy for performance across a wide variety of tasks."
"The latest 'OS X is slow' meme to impinge on the mass psyche of the Internet comes courtesy of one Jasjeet Sekhon, an associate professor of political science at UC Berkeley. The page has hit digg and reddit and been quoted on Slashdot. Is there any merit to this?"
Jasjeet Sekhon benchmarked Linux and MacOS X on the MacBook Pro using his statistical software, and finds that "Linux is found to be much faster than Apple's OS X for statistical computing. For example, in one benchmark Linux is more than twice as fast." Earlier, he ran tests on a G5 and an Opteron, and conlcuded: "Those results were terrible for OS X and not particularly good for the G5 (970) chip. For example, my 2.7 pound Pentium-M Linux laptop is faster than my 44 pound G5 running OS X. The floating point performance of the 970 chip leaves much to be desired, but OS X makes the performance problem significantly worse."
"There are a lot of Linux filesystems comparisons available but most of them are anecdotal, based on artificial tasks or completed under older kernels. This benchmark essay is based on 11 real-world tasks appropriate for a file server with older generation hardware (Pentium II/III, EIDE hard-drive)."
"The only benchmark where the PowerPC-based Mac mini outperformed the Intel-based Mac mini was Stdlib Allocate, which is also the only benchmark where the PowerBook G4 outperformed the MacBook Pro. The Stdlib Allocate benchmark depends more on standard library performance than raw hardware performance. It's also worth mentioning that the Intel-based Mac minis were, for the most part, faster than our baseline system (a PowerMac G5 1.6GHz). Yikes. Overall, we're impressed with the Intel-based Mac mini's performance."
According to a benchmark, Sun's Niagara processor is over 4 times faster at serving dynamic PHP pages than a dual Xeon server. "We did real production benchmarks using different servers. Servers were put into production behind load-balancers, then weights on load-balancers were changed so we got highest number of dynamic PHP requests per second. It must sustain that number of requests for some time and no drops or request queue were allowed. With static requests numbers for Opteron and T2000 were even better but we are mostly interested in dynamic pages."
"The other day I posted an article to highlight our new benchmark application Geekbench. It received a lot of attention, but there was some concern about the machines used in the testing (mainly, the Athlon 64 and Pentium 4c are kind of old). Despite the fact that the article was meant to be more about the testing than the results, some people refused to let it pass. Luckily, a few people responded to my request for results from more machines, so here is a smaller article comparing just three machines: a PowerMac G5 Quad, an Athlon 64 X2 and a Pentium D."
GeekPatrol puts their new cross platform benchmarking tool to work and compares 12 machines including the new iMacs, PowerMacs, an Athlon64, a P4c, and a Xeon. "The PowerPC G5 is still a good processor. In fact, it’s still a great processor. Apple isn’t switching to Intel chips because Intel chips perform better, but rather because a G5 would melt through the bottom of a laptop. The Athlon 64 edged out the Pentium 4c on all the CPU tests, while the Pentium 4c edged out the Athlon 64 on all the memory tests. It seems to me that Intel and AMD have had their different strengths all along, so I don’t find this surprising. The Intel Core Duo is a great processor. It performed as well or better than the PowerPC G5 at similar clock speeds (1.8GHz and 2.0GHz), and has nowhere to go but up."
"Ok, that headline may be a bit overblown - but Microsoft Research has released part of a report on the Singularity kernel they've been working on as part of their planned shift to network computing. The report includes some performance comparisons that show Singularity beating everything else on a 1.8Ghz AMD Athlon-based machine. What's noteworthy about it is that Microsoft compared Singularity to FreeBSD and Linux as well as Windows/XP - and almost every result shows Windows losing to the two Unix variants."
This is an interesting comparison of OpenOffice 2.0 Calc and MS Office 2003 Excel. The author found that OOo is slow in some operations and takes a lot of RAM & CPU.
"We received reports that GNOME was orders of magnitude slower than CDE on Sun Rays. To verify and measure this, I designed and ran some performance tests in order to compare the time and bandwidth usage of GNOME (JDS) with that of CDE on Sun Rays. The tests measure the time it takes to display data using various desktop applications: Browser, StarOffice and Terminal." Read more here.
Anandtech did an excellent job benchmarking some of the latest CPU's from IBM, Intel, and AMD. This is primarily aimed at server performance, but some interesting details surrounding Mac OS X surfaced.
According to Apple, "...unmodified applications that use the system math functions will get an automatic performance boost on the G5..." when switching from Panther to Tiger. BearFeats decided to run some tests to see if they got a speed gain right out of the box with applications that we suspect use system math functions.
Xen is a relatively new technology to enable several virtual machines (domU) to run on one computer. The purpose of this article is to determine what operating system (NetBSD or Linux) should be selected as domain 0 (dom0) operating system to get the best performance when running several CPU and disk intensive virtual machines at the same time.
HP and the Pacific Northwest National Laboratory (PNNL) have collaborated on a new 11.8-teraflop Supercomputer for the Department of Energy. The $24 Million HP Supercomputer uses the Linux OS and Intel's Itanium2 processors.
