:Also FreeBSD only caches a limited number of directory blocks. This
:was discussed on -hackers in April. Search for the subject "Directories
:not VMIO cached at all!". Matt Dillon posted a patch to to better
:cache directories (at the possible expense of wasted RAM and which breaks
:NFS) in Message-ID <[EMAIL PROTECTED]>.
That's been committed, but you have to turn it on with a sysctl
because softupdates occassionally barfs with it on. It seems unlikely
to me that it will effect the benchmark unless the benchmark creates
a whole lot of directories.
sysctl -w vfs.vmiodirenable=1
The NFSv3 performance elements have also been committed. I'm going
to try running this benchmark thingy on my test boxes as soon as I
can get my cvs tree updated.
