Re: pfil and network performance

I found that UDP rules with keep state caused very slow write 
performance on AFS.
I modified my rulesets, removed all "keep state" for both pass in and 
out UDP rules.
We still use keep state (and keep frags) on TCP rules.

Dunno about NFS, thought this might be worth a try for you.
