I wrote a simple benchmark that just prints a number of lines on the console. Java uses about 180 times more CPU on the second level when compared to first level. It uses about 40 times more CPU than Perl doing the same thing on second level. When I turn the JIT off the CPU time on the second level is slightly less than with the JIT on, but the wallclock time is cut by half. > This is probably too specialist topic for general consumption. I find this pretty fascinating, not sure about the others. If no one else replies let's move this offline.
