OpenSolaris vs. Linux Kernel Benchmarks
Written by Michael Larabel in Operating Systems on 14 May 2009. Page 9 of 9. 27 Comments

Ending out our tests, Ubuntu 64-bit reclaimed its lead at simple image resizing with GraphicsMagick. Nexenta came ahead of the Ubuntu 32-bit on the Linux 2.6.24 and 2.6.30 kernels.

In a majority of the tests, Ubuntu came out ahead of Nexenta CP2, which is based upon largely the same packages but incorporates some of OpenSolaris at its core. In some of the tests where Ubuntu took the first place position, the lead over Nexenta was very evident and huge.

Our focus of this article was to just compare the OpenSolaris kernel performance to Linux via Nexenta, but from these graphs some more information can also be gathered in regards to the 32-bit vs. 64-bit performance and the older Linux 2.6.24 kernel against the up and coming Linux 2.6.30 kernel. The Linux results should be even faster when switching to a newer Ubuntu release like Ubuntu 9.04 that includes a newer release of GCC and other key packages.

These results can be discussed in the Phoronix Forums and you can run your own tests on Linux, Mac OS X, OpenSolaris, or BSD using the Phoronix Test Suite.
