>Our PC have 1GB RAM, the user's PC has 256 MB.

To create comparable scenario, create another bootoption in your boot.ini
with /maxmem=256

Take a HARD look at installed OS / protocols. In some scenarios just having NetBEUI as well tripled performance. Verify same netork speed and single/duplex setting. Also check Pathing issues - especially id you were testing in the IDE and have code working of version(2).

On the user machine, check the temp location, amount of free space, defrag to get continuos space. Check compression/encoding settings on the target folders. Kill *everyting* living/moving in the task bar - that includes the firewall and AV for at least a few test runs. Run with task manager visible besides the form and kernel times showing.

UPDATE:
the view dbc locally can help big time, but the differences will mostly be seen when running many users concurrently. Temp dir I consider part of pathing <g>, but I assume the exe is running locally ? give it a nice config.fpw
