How to profile branch prediction hitrate in Java


Is there a tool available to profile java applications regarding branch (mis)prediction statistics for if statements?

I know VisualVM and JDK Mission Control but did not find such functionality.


Solution

  • No such tool exists.

    It is generally impossible to extract that information from CPU, you can either measure performance of code block, or emulate execution of code and collect such statistic.
