> Take the advice in tuning(7) with a grain of salt because a number of suggestions are really outdated. I know because I filed a PR last night after I saw how out of synch some of the defaults it claimed were with reality on 9.x+. And I know other suggestions in the manpage are dated as well ;/.
There is a wiki page http://wiki.freebsd.org/SystemTuning which is
currently more or less tuning(7) with some annotations, the idea being
to sort out whats outdated/invalid with an aim of rewriting tuning(7) to
be more accurate and useful. I'll grab any info in your pr thats not up
there already to keep it updated if thats ok.
