Let me make a couple of things absolutely clear: 1) FreeBSD has supported large files for years before commercial versions of unix have, and now that they do they have yummy interfaces like stat64. I think Linux finally got around to large file support about 6 months to a year ago. 2) FreeBSD (*BSD) filesystem performance is quite acceptable, some commercial variants exist that outperform it, but there's useless microbenchmarks to prove either way. 3) FreeBSD filesystem stability is a reality unlike under linux where you really have no choice when it comes to a stable and fast filesystem. You can run unproven new systems such as Reiser or ext3, or you can pay through the nose for systems like Veratis volume manager suite. 4) FreeBSD has supported SMP for at least 4 years now. The kernel is still mostly non-reentrant right now, but it's getting there. 5) For someone who seems quite sure about the "dwindling marketshare" of FreeBSD you sure haven't done a lot of research. Lastly, if you want to complain about BSD without contributing anything you can reach a much wider audience of lamers (like yourself) by posting here: http://www.slashdot.org/ Other fun things to post about are: "First Post." "Natalie Portman." "Relative merits of the GPL versus gargonzola cheeze." "How sun spots are contributing to the death of *BSD." happy hacking, -- -Alfred Perlstein [alfred@freebsd.org] Ok, who wrote this damn function called '??'?
