increase nfsd
ps -ef | grep nfsd
usually default is only abt 16 threads, if you have a lot of resources can try go for 32, 64, 128, 256 etc... usually I stop at 128 is sufficient
why?
because tuning is not a magic bullet, tuning is abt increasing resources in one area while decreasing and taking it from elsewhere.
vi /etc/rc3.d/S15nfsserver(search for nfsd)
increasing nfsd usually to make it perform better as in able to handle more request not necessary faster, how fast it will be will depend largely on your network.

NFSD(8) BSD System Manager's Manual NFSD(8)
NAME
nfsd -- remote NFS server
SYNOPSIS
nfsd [-6rut] [-n num_threads]
DESCRIPTION
nfsd runs on a server machine to service NFS requests from client machines. At least one nfsd must be running for a machine to operate as a
server.
Unless otherwise specified, four servers for UDP transport are started.
The following options are available:
-r Register the NFS service with rpcbind(8) without creating any servers. This option can be used along with the -u or -t options to
re-register NFS if the portmap server is restarted.
-n Specifies how many server threads to create. The default is 4. A server should run enough threads to handle the maximum level of
concurrency from its clients.
-6 Listen to IPv6 requests as well as IPv4 requests. If IPv6 support is not available, nfsd will silently continue and just use IPv4.
-t Serve TCP NFS clients.
-u Serve UDP NFS clients.
For example, ``nfsd -t -u -n 6'' serves UDP and TCP transports using six threads.
nfsd listens for service requests at the port indicated in the NFS server specification; see Network File System Protocol Specification, RFC
1094 and NFS: Network File System Version 3 Protocol Specification.
The nfsd utility exits 0 on success, and >0 if an error occurs.

The nfsd utility first appeared in 4.4BSD.
