Subject: Speed up saving of profiling data by 27x
X-Git-Tag: 0.4.14~542
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5c3546e459ede7fbdfc22b340ed6b2af5073ec5b;p=oweals%2Fminetest.git

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.
