Does messing with the HZ on FBSD make utilities like top inacurate like I have heard it does on linux? Also what file is this setting in on FBSD?
Lastly is "options LINPROCFS" an option i going to see in the kernel compile? Or are you talking about setting it somewhere else?

Have you got any performance metrics on the new scheduler I've heard some bad things about it so have stayed clear. 5.1 is defo one u want for SMP but 4.8 is quicker on single proc. Watch out for the fact the it treats it as 4 * CPU which means that when top shows 50% idle it is using 100% of both physical CPU's With hyperthreading active "machdep.hlt_logical_cpus = 0" not "machdep.cpu_idle_hlt = 0" you should get down to about 30% idle before seeing bad effects but its very subjective. Setting a higher HZ kernel does produced a definite decrease in ping and increase in FPS at the experience of CPU load so you might want to experiment with it moving it up in HZ in say 100 inc's till your happy with it. For HL ensure u set "stats 0" or add "options LINPROCFS" and mount it.
