I just recently worked with sun solaris 10 and found it to be reasonably performant without much tuning. This was on a dual sparc sunblade workstation which i felt was very well engineered. I was able (with zero solaris experience) to get postgresql up and crunching away at some really data intensive tasks while running an application compiled their very excellent fortran compiler. In the enterprise world I am finding that the only linux distrubutions supported are redhat and suse, meaning if you have a problem with your san running against your gentoo box you have a serious problem. Solaris OTOH, is generally very well supported (especially on sun hardware) and is free. So I give sun great credit for providing a free if not necessarily completely open platform for developing open source applications in an enterprise environment. Merlin
