Google "web site load testing" to learn about the subject. You can do
something cheap and dirty with VFP, or pay a company for far more
precise testing.

If you're worried about your bandwidth use, you should also look at
slimming down the load on your pages by cleaning up your HTML by
pulling out the JavaScript and CSS into separate files,  stripping
excessive HTML with tools like Tidy.

So, the dynamic module is crashing the http server? There are a couple
of tactics to consider:

1. Fix the dynamic code so it doesn't crash.
2. Split the site to use more than one http server, and run the buggy
code on only one of them.
3. Put a caching web server like squid in front of the dynamic web
server, so it can more rapidly serve the static content and pass the
dynamic requests on to the web server.
