Benchmarks "Earlier this month we published an article looking at the Linux versus OpenSolaris performance when using the new AMD Shanghai Opteron CPUs. Ubuntu Linux was faster than OpenSolaris 2008.11 in nearly all of the tests, but as mentioned in that article, OpenSolaris is still dependent upon GCC 3.4 where as Ubuntu and most other Linux distributions are now shipping with the newer and much-improved GCC 4 series. Following that article being published, Sun Microsystems had requested some compiler tests since they were confident the results would be different had their Sun Studio compiler been used. Well, in this article we now have some OpenSolaris benchmarks from the same AMD setup using GCC 3.4, GCC 4.0, and Sun Studio 12."

Sun Studio Compiler. --- AVOID! AVOID!

If your working on Linux AVOID this.

We tried this on a project at work and it was a huge mess.

In order to use their compiler you then have to deploy ALL SORTS of custom libraries like custom version of libC etc... its nasty and makes a mess of your system.
