in reply to Getting Loaded

You need to tell us more about your requirements. How much traffic; what kind of application; how many servers, etcetera.

There is the Linux Virtual Server project for making a load balancer. I don't know how far that will scale. The right commercial loadbalancers can easily scale to hundreds of megabits per second and many thousand requests per second. I have good experiences with that using equipment from Foundry Networks (http://www.foundrynetworks.com/).

If you are using CGI now, the first thing you should do to scale better would be installing mod_perl.

The best way to scale MySQL (and other SQL databases) is by caching as much as possibly as close to the application as possibly. http://develooper.com/modperl/
