I believe you wanted to test out for sure to see how much bandwidth you were realizing at YOUR SITE. I will predicate the rest of my post by saying my method might sound a bit amateurish but it will work and i have used this. I've found the best way to do this is actually go to a windows box and use this tool called FlashGet, load it up with downloads (from various sites, for load balancing) www.easynews.com can take allot of abuse if you have an account, and then download. You should probably test several times during the day. Perhaps once before business hours, immediately before lunch-hour, and late night after hours, to see what kind of bandwidth you can realize depending on the load. (If he's not overselling then you should find that the bandwidth you're getting is reasonably consistent) The reason I suggest FlashGet for WinTel is basically it's a pretty good download manager that has a ton of options which make it easy for these kinds of tests. I've gotten this combination to saturate a T-1 before, so perhaps you should let people know you are about to "test" out some stuff that might knock them off for a few minutes. Now if you don't have some kind of third party tool measuring your bandwidth, you'll have to sit around watching the bottom "status bar" looking at the bandwidth measurements, but like I said this is a pretty quick and easy (not to mention cheap) way to test out your bandwidth.
