Website/Server Stress/Bandwidth Test...
 

How would one go about seeing how well your shared hosting holds up with multiple users and a lot of bandwidth (downloads)? I know lots of hosting companies offer all sorts of packages, many with unlimited bandwidth. But how will their servers hold up if I have a popular site that could have a large user base and lots of bandwidth?

I thought of hosting some free porn, but don't want to violate any terms with my hosting company.

Any ideas?
