Are you saying this from actual experience or from reading other people's comments? If it is from actual experience and XYZ version of Linux does a particular job better then I don't see why you should not consider using what works best. As someone who has had to use Redhat for over a year because that is what this job uses... I would trade some performance for not having to deal with all the peculiarities in Linux distros. Also, as mentioned in the slashdot article discussion, some of the reasons Linux may do better on some operations are a tradeoff between stability/security and speed. http://linux.slashdot.org/comments.pl?sid=1384455 >From having to use Linux I have found some instances where FreeBSD may no not be up to par (ie Java), but overall I would much rather use FreeBSD if I had a choice. "Features" like the OOM killer are, in my opinion, extremely poorly designed and likely worst executed.
