nfs is set to work over TCP.
What mount options are you using ?
I use something like the following
172.18.23.34:/backup/backup2 /offsite-backup nfs
rw,-r=32768,-w=32768,tcp,noauto
in fstab

We've had good luck with the following options:
rw,tcp,intr,noatime,nfsv3,-w=65536,-r=65536
along with the following in /etc/sysctl.conf
net.inet.ip.fastforwarding=1
net.inet.ip.intr_queue_maxlen=5000
kern.ipc.maxsockbuf=8388608
net.inet.tcp.sendspace=3217968
net.inet.tcp.recvspace=3217968
And, finally, turning on polling on the interface on our disk array.
We are getting a solid 300 Mb/sec on a GigE link.
Regards,
Mike
