NFS performance tuning?

[Lev Serebryakov]

Hello, Freebsd-net.

  I have two systems (7-Stable), connected with gigabit link. iperf
shows 667 Mbits/sec on TCP and 600Mbit/s on UDP without any tuning.

  But NFS gives me only 17Mb/s (~136 Mbit/s) on sequential read of
very big files, and about 8-10Mb/s on "real" workloads.

  Are here any guides how to tune NFS for performance?
