Hello.
I'm a computer science professor at Northern Michigan University. I found your email address at http://en.opensuse.org/OpenSUSE_Testing_Core_Team. I'm considering offering a student research project and thought you might be able to provide some input. Or, could you suggest someone better to contact?
Has anyone timed various operations in Suse vs Ubuntu vs Fedora? I'm curious if it's quicker to log in, find a file, open a document, etc. in Suse, Ubuntu or Fedora?
Does anyone already have data on these questions? Or, if we do the benchmarking myself, is anyone interested in the results? Finally, is there some particular operation you'd like to see benchmarked?
I'm copying this reply to the opensuse-testing mailing list.
I have heard anecdotal reports that distro XX is faster than YY while doing ZZ, but I am not aware of any properly designed studies. I am confident that the other members of the Testing Team will post such studies if they exist.
The Phoronix test suite ( http://www.phoronix-test-suite.com ) allows to benchmark many things on UNIX systems (disk, compilation, SQL, 3D, ...) for free. They frequently post the results of some benchmarks in their articles site ( http://www.phoronix.com ). They say they are going to post a big test with many OSes soon. These tests does *not* include boot times, and no specific GUI application is tested (like, say, firefox); GUI tests measure things like 3D performance and GTK+ performance. You can use bootchart to test boot times, so you can measure the various components of boot time. I think testing specific GUI applications like, as you say, «open a document» would require support by the application itself (if you don't manually measure the time with a chronometer), so this could be difficult to do.
Certainly, the distro packagers would be interested in the results. My suspicion is that the most important factor will be the kernel itself, and that there will be only small differences when all are using the same kernel version; however, that is certainly a testable hypothesis.
