Load testing can be harder on the client side than the server side at high loads, which might be surprising, but consider how many servers need to handle large numbers of clients connecting and how few clients need to connect to large number of servers --- if you do it yourself, you're going to have to relearn all the techniques to make large number of connections possible.
If your desired load for testing is small, it's not a big deal, of course.
