Occasionally I have to do some profiling work on Java code, and I would like to know why I should have my boss investigate in a commercial profiler as opposed to just use the one in Netbeans or JConsole?

What would the killer features be that would warrant the investment?

I've not used Netbeans profiler, but tried JProfiler, Yourkit and JProbe. I found Yourkit slightly better (mainly bought by the usability aspect). Some of the useful features in it are: (you can check if it is available in Netbeans)

  • J2EE Profiling (Eg. It shows how much time an SQL query took).
  • Snapshot comparison and annotation
  • Deadlock detector
  • Exception telemetry

You can check for more details at their site.
