I use 16384 for 100Mbit at work which seems to be a decent size vs
reponse ratio.

I have a few standard bonnie results of linux -> linux tests on my
homepage http://iserv.nl/
They are a few entries down and is in the following config.
Server was a pIII 450 with 256MB of ram and a 2c905B NIC and a
40GB IDE disk in UDMA33 mode. I used 8 nfsd processes and enlarged the
buffer size from 64KB to 256KB.
echo 262144 > /proc/sys/net/core/rmem_default
echo 262144 > /proc/sys/net/core/rmem_max
Client was a Dual PIII 733 with 256MB ram and a Intel eepro100 NIC.
The limiting factor was wire speed though.
You may note that the speeds I was clocking on this desktop machine with 1
IDE harddisk in UDMA33 mode on a i440BX motherboard are higher then your
scores for the server.
However it seems Linux and XFS is a fast combo for large databases. We
needed to do a dictionary update of our databases (6GB total) and since we
have a testmachine (the PIII450 Desktop model from above) and Progress 9
we could simulate the entire process.
The production server is a dual PII400 with 512MB of ram and 45GB of disk
in raid5 under NCR MP-RAS (SVR4) and Veritas FS.
The conversion was done on the sunday when there was nobody in the office
and the machine was totally idle. The testmachine was during a workday and
about 2 people were busy upsetting the printing system (including me
Yay!).
The conversion under linux took 35 minutes and the machine was responsive.
The conversion under NCR MP-RAS took 6 Hours (!) and the machine was
stuttering along :-(
My manager urges me to make the migration from the NCR to Linux machine on
a faster schedule. No more convincing left to do. The new machine will
be much faster then the current desktop machine so he also took this
oportunity to take a vacation.
Hope you get some more info.
Cheers
Seth
