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 o= n 9.x+.

Please take my suggestions (apart from the networking sysctls) with a grain of salt as I didn't look at the sourcecode for the filesystem ones (I was going off the top of my head and other emails I had seen passed around). I'll update the tuning 'wiki' with mention of the new networking defaults. If we want to make this manpage 'timeless', should we remove mention of defaults and go off basic guidelines (if you set this higher, you'll get better performance in scenario, X.Y.Z, etc)? Thanks! -Garrett
