I've got a FreeBSD NFS server behind two FreeBSD webservers (all 4.9) who load all their pages from the NFS filesystem and I'm seeing less traffic from the NFS server than I expected. The webservers are serving 20Mbit/sec of traffic while the NFS server is only sending 1Mbit/sec of traffic. I know the bulk of the traffic generated is static pages/images off the filesystem. Does FreeBSD's NFS implementation allow for caching of documents on the client side, either its self or through the VM system's inactive pages? The reason I'm asking is that I'm trying to size an NFS server using a few of many similar sites that I hope to cluster. The performance so far has been great, but I'm worried that there's something I'm missing here that will cause the performance/usage to change in a very nonlinear way. Any thoughts on the subject are appreciated. -- Michael Conlen
