I'm looking for a decent free/low-cost load testing tool that I can run from my LEBs to verify the performance of a production site. All I really need to be able to do is simulate a number of concurrent users navigating through a number of pre-set paths, with a little bit of randomness thrown in for good measure.
Never really been involved in anything like this, and Googling brings up a lot of options, so I'm not really sure where to start. Does anyone have any recommendations?
