>User are not just sharing datafiles over the LAN, but EXE too? If so, increased demand for data will slow access to the parts in the EXE. Move the exe to the local workstations using a loader/launcher and screens will refresh faster. Less load on the LAN will give better performance for data access too.

There was a neat old trick for this on slow networks: make the exe read-only. It's not network access per se that's slow, it's the checking for locks. Since nobody is changing the exe (but the installer), setting it read-only will just tell the network not to bother with locks.

Last time I did this, the network took off. Those XT and 286 machines had to be tethered to the desks.
