Thanks for your advice -- seems i have been too chicken-hearted. Summary: Don't bother with tuning the server and don't even think about setting up a cluster for something like this - definitely overkill. ;o) That's what i'll do ;-) However the 50/150 concurrent requests are a guess (best i can

Hello, please excuse my general questions. A customer asked me to setup a dedicated webserver that will offer ~30 files (each ~5MB) for download and is expected to receive a lot of traffic. Most of the users will have cable modems and their download speed should not drop below 50KB/sec. My
