in this node, someone mentioned that one of the major reasons for PerlMonks' sluggishness is that its servers run freebsd instead of linux.

well, why? if freebsd is known to handle threads poorly and thus slow down MySQL, then why on earth are we still using it?

    The problem is just as much with MySQL as with FreeBSD. You might just as well ask why we're not dumping MySQL.

    FreeBSD is nice. It is what pair.com uses. That's why.

        Which is an absolutely awful design decision, but that's another debate :-)

    Actually, most of the problems with MySQL on FreeBSD have been worked around already.

    I got a hint that the recent slowness was due to memory exhaustion, but I need to check that.

    Quite simply: it's not in the hands of Perlmonks. Perlmonks is graciously supported by pair Networks, so what we run here is on their box. Scroll to the bottom of any Perlmonks page to see the site's copyright/partnership text.

    There is a port of the linux threads library to FreeBSD and MySQL can be complied with them. This feature is marked as experimental but I know several quite heavy loaded sites that run for quite long time in this configuration. And yes, it is noticeably faster (especially on SMP boxes where FreeBSD 4.xx's threads suck).

    Also I don't know what table type is used on perlmonks but for some applications replacing MyISAM with InnoDB causes significant speed up.

    From what I understand, threading in Linux is nothing to write home about, either. At least until 2.6/3.0 comes out... is FreeBSD that bad? I'm just kinda curious, can someone point me to a writeup/comparison of a technical nature, on the subject?
