New page

I do it with a special profiler class in my [[EvBotNG]] which is the part of my framelib. You can see the profiler class at [https://github.com/evgmik/robocode_bots.frame-lib/blob/master/misc/profiler.java profiler.java]. The examples of it use are sprinkled all over [[EvBotNG]]. In the essence, when you need
to start a timer for some code you say <code>profiler.start( "methodName" )</code> and then at the end of the profiled code you say <code>profiler.stop( "methodName" )</code>. Once you ready to see the stats, you call <code>profiler.formatAll( )</code>.
I do it at the end of every round.

This will print a nice looking statistic table which shows nested profiled chunks in a tree like structure. Something like
