Subject: [PATCH] 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.
