Hi John,

While it is true that the kernel based NFS under Linux is (still) weak,
the userland version works just fine for us. We run a 160 GB RAID disk
off a dual SMP Linux bax out to approx 250 unix hosts (nfs) and 50 or
so Win boxs (samba) in the dept without problems with decent response
times. The disk contains all user $HOME's, the mail spool, and
common application binaries for various architectures.

knfs was stripped out and ol'faithful userland nfs used instead.

Traffic stats for the machine (daily, weekly, monthly, yearly) can be
viewed at:
