Thanks for you comment. I ran startProfiler yesterday. It ran for about 10 seconds and then it just re-displayed the prompt. As I understand it, the profiler should write a log file that can then be analyzed by something. Honestly, I thought the readme was very conusing to someone who had never profiled an application before. I am guessing the agent is the piece that runs on the server and will collect method execution time, memory usage, etc... I am not sure what "Running the example" means from the readme.txt file. I am assuming "Running the Client" means that it will collect the data the server is spewing out as it runs. The output of the client I am assuming is a file of some sort that can be analyzed by something else or possibly the client itself. I am not sure. Anyway, as I said before I ran startProfiler and it ended... The server is running with the profiler enabled. Is there some sort of documentation other than the readme.txt for someone who knows nothing about this and needs a clue?
