AMD Shanghai Opteron: Linux vs. OpenSolaris Benchmarks

In our first two tests, LAME MP3 encoding and Ogg encoding, Ubuntu 8.10 was the fastest operating system. Ubuntu 9.04 was running slightly slower than the Intrepid Ibex, but in both encoding instances OpenSolaris 2008.11 was running much slower. OpenSolaris 2008.11 had required significantly more time at encoding the audio files -- over 60% longer in the case of the Ogg test.

Ubuntu 8.10 was faster than Ubuntu 9.04 by a very small amount, but again OpenSolaris 2008.11 was last at the timed PHP compilation. OpenSolaris 2008.11 is using the older GCC 3.4.3 version compared to Ubuntu using the latest GCC 4.3 branch, but OpenSolaris was just running a few seconds slower.
