As a guess I'd say your output is listing the methods called in each running thread, the number of times it was called and the percentage of total CPU that they each used. But that is just a guess.
As an alternative I'd recommend taking a look at JVisualVM. It'll be a lot easier then profiling via the command line. Goto the bin folder of your JDK (approximately: C:/program files/java/jdk1.6.0_17/bin) and you should see 'jvisualvm.exe'. Run it and wait for it to open. Then run your game/app and it'll appear listed on the left. You then double click on it to get JVisualVM to connect.
Once it's connected you can see the memory and GC usage as well as setting it up to profile your app in greater detail.
Ok thanks, I'll try it out now!
Edit: I have to to say this thing looks pretty cool, I'll get back to you once I understand how to read the charts in it, for some reason the "Memory" in the profiler is taking ages to load(still not loaded) but other things look good. Thanks again for the help =)
