Hi, 

I have a freebsd machine which writes VERY slowly to an
remote NFS directory exported from a DEC server machine.
A simple cp of 400Kbytes take 4-5 seconds. When using rcp
instead, it is faster at 0.6s. Hence the underlying tcpip
connection (cabling, etc) is OK. Could it have to do with
the local freebsd NFS client buffering/caching? How to test
and set properly?

Also, another Linux machine which reads from the DEC file
system is reading old copies, possibly from its local cache.
The DEC server has its NFS "properly" setup, with NFSD set to
8 and NFSIOD set to 7. With 64MB ram, it is more than enough
to service NFS requests from just 2 machines.

So all things point to an improper NFS client setup on the
freebsd and linux machines.

Appreciate any suggestions and help,

Kind regards,
Kong Wah
