We have some in-house developed applications where a Windows client
interrogates a Linux server. These applications work fine on a network
running at reasonable speed however on slow networks eg GPRS in a poor
signal area the performance becomes worse than expected. I have been
making some changes recently but reports suggest I have managed to make
things worse not better. Ideally I would like to have a small test
network (which could be as simple as a crossover network cable)
connecting two computers) where I could in some way vary the speed
between normal operation and something like 1000 bits/second; preferably
with some intermediate points. Any ideas how to achieve this?
