Speed up saving of profiling data by 27x

On Windows Release x64 bit build this changes: ProfilerGraph::put 1.68% -> 0.061% ProfilerGraph::draw 12% -> 17.% So yes, there is a tradeoff between saving profiling data (executed always) and drawing the profiler graph (executed very rarely). But usually you don't have the profiler graph open.
