"The server and workstation oriented benchmarks we ran in this article across these three distributions were Apache, PostgreSQL, SQLite, Dbench, IOzone, Threaded I/O Tester, C-Ray, GraphicsMagick, John The Ripper, timed MAFFT alignment, GROMACS MD, NAS Parallel Benchmarks, and SPECViewPerf 9. All of these tests were run through the Phoronix Test Suite with Bardu Beta 1. CentOS 5.4, OpenSuSE 11.2 RC1, and Ubuntu 9.10 were all tested with their default packages and settings, with the exception of disabling SELinux on CentOS.
"CentOS 5.4 is shipping with an updated Linux 2.6.18 kernel, GNOME 2.16.0 desktop, X Server 7.1.1, NVIDIA 190.29 display driver, GCC 4.1.2, and uses an EXT3 file-system by default. OpenSuSE 11.2 RC1 runs with the Linux 2.6.31 kernel, GNOME 2.28.0, X Server 1.6.5, NVIDIA 190.29 display driver, GCC 4.4, and uses the newer EXT4 file-system by default. Lastly, with Ubuntu 9.10 we have the Linux 2.6.31 kernel, GNOME 2.28.0, X Server 1.6.4, NVIDIA 190.29 display driver, GCC 4.4.1, and an EXT4 file-system. For all three Linux distributions we were using the x86_64 builds. The final releases of Ubuntu and CentOS were used, but due to OpenSuSE 11.2 not yet being officially available, we had used its first release candidate. The hardware for this test system was made up of an Intel Core 2 Duo E8400 clocked at 3.00GHz, a Gigabyte EP45T-DS3R motherboard (P45 + ICH10R), 2GB of DDR3 memory, a 160GB Western Digital WD1600JS-00M, and a NVIDIA GeForce 8600GTS 256MB graphics card."
