I'm using NFS quite extensively in with FreeBSD 1.1.5.1. I am using
16bit SMC ethernet cards, which give very good performance.
NFS reads give 500K/sec to 650K/sec (if your very lucky) between 2
1.1.5.1 boxes, and writes are 100K/sec to 150K/sec. (according to
iozone.) -- 500 to 500K/sec is generally typical.
I haven't been able to test things much, but a FreeBSD 2.0 client seems
to get slightly better performance than a 1.1.5.1 client -- this will
need more testing though, as my 2.0 system is shaky at best at the
moment.
I am getting similar (and generally slightly better) transfer rates
when the FreeBSD boxes are served by either a Sun IPC or a SS10-512.
a critical factor is to have a fast ethernet card, where Western
Digital clone cards (preferably 16bit) give the best performance.
As far as TCP performance goes, a machine like this rates roughly
equivalent to and sometimes slightly better than a Sun IPC, and miles
better than a SparcClassic.
The NFS performance is not quite as good as a Sun IPC.
Geoff.
