Hi,

Just to try the "thing" out i did put vfs.ufs.dirhash_docheck to 1.
My active memory use was in 30 minutes 75 MB lower, and the io is 
faster, the load is lower.
The OS is FreeBSD 4.5-REL with 1250MB ram on a PIII 733, it runs 30+ 
active jail() enviorements.

What does it exactly, this hidden sysctl value?
