network performance
Have icl sparc teamsever and 750i teamserver running svr4 and SCO respectively. both on same dual 10T network.
NFS mounting of disks between machines runs like a dog - slower the telnet / tcpip connections.
No possibility of introducing a dedicated network for NFS links, or introducing 100T cards - due to software conflicts with faster cards. Any views on how to speed the connections up?

Yoy may use a switch, instead of hub, to have interconnection in LAN between involved machine.
What version of SCO? There are some patches that address NFS on SCO.

http://www.psc.edu/networking/perf_tune.html does not cover SCO or SVR4
What version of SCO are you using and what patches have you already applied. There are only a couple of NFS tuning parameters that may need adjusting. Are you using 3.2 or OSR5? If you are using OSR5 5.0.4 then make sure you have applied oss469c. It made a world of difference in NFS performance on my SCO boxes.
SCO Openserver or SCO Unixware? Which version?
How big is the mount filesystem?

If it turns out that it's not a configuration issue and it's a network contention/throughput issue you could try
the following relatively low cost approach:
add another 10baseT interface to each of the machines,
connect them to each other via a cross-over cable and
configure them for full-duplex operation.
This way they would have a dedicated 10 Mbps (well... ~7Mbps actual throughput) link each way.
