That's great. There is someone who has done this previously, but his company won't release the code to Apache. It's frustrating that someone else has to do it all over again. > Basically I have two problems: > > 1. I have to deal with unique users. > Instead of a thread group, I need a user group.

When you say you need unique users, I'm not exactly sure what you mean. Each user/thread in JMeter gets its own thread, and runs independently of the other users/threads. If you need each user to do different things, there are ways to do that too, though they are more limited. There have been some recent enhancements that have improved this ability. You should, at least, describe more fully what you mean before jumping into this one. > > 2.
