Nice profiling of the entire call stack trace, no log lookup needed Helps find slow methods and queries /memory leaks quickly Live debugging of a session is the icing on the cake Most projects have a development phase and then it goes for performance testing. With single user profiling done by Jprofiler and issues fixed, application stands a much better chance of withstanding performance tests. This is my opinion saves a lot of rework and last minute changes Morever developers get to see the entire call trace which helps them decide where to put logs effectively. This reduces the time taken to troubleshoot issues The live debug feature is especially useful when we have API and web services spanning several sources like in the case of market data aggregators Review collected by and hosted on G2.com.

None to dislike. Makes single user load testing smooth In fact one of the god ways to read code is to turn the profiler on while running through the application. helps find the UI with the backend modules Review collected by and hosted on G2.com.
