No. Lack of ACCESS caching makes us slow and eats the network (because we are very good at generating/sending/receiving them). If there's someone out there that wants to work with the very best NFS people in the business to sort out our problems, please let me know. NetApp are keen to see our issues resolved (it will mean less angst for them in the long run, as they have many FreeBSD-using customers). Right now, we are accumulating a bad NFS reputation. 8( > Brian Feldman > > On Wed, 14 Oct 1998, Mike Smith wrote: > > > > another known problem exist for nfsv3 > > > > > > we use www server working over nfs with about 1500000 hits/day > > > it work fine with nfsv2 (load 0.1 - 0.8), but with nfsv3 > > > we see load > 130 and server replay is very slow ... > > > i think this is a bug in fbsd nfsv3 realization, the > > > same scheme with solaris/sparc nfsv3 client/server work > > > without this problems ... > > > > The problem here is almost certainly that we don't cache the results of > > ACCESS RPC calls.
