Setting up a file server

Previously, you provided me with some advice for improving NFS performance. I tried cat /proc/net/rpc/nfsd and the following:
 rc 27 1990131 248684
 fh 0 2238443 0 0 227
 io 1932368455 3377147869
 th 8 0 197.180 0.220 0.120 0.000 0.300 0.200 6.220 0.010 0.000 0.000

Is that okay for a good fileserver?

Do you recommend any changes in NFSD?

You're using the default amount of threads for a Solaris system. Unlike the old TV show, eight is not enough here. Try 64 -- there are no memory issues you need to worry about if you're not really using all the threads. There are two ways to do this.
  1. Use this command: pc.nfsd 64
  2. RPCNFSDCOUNT=64 in /etc/rc.d/init.d/nfs
