A CS# Benchmark Plugin
Simply drag and drop the addons folder into your server game directory
Set the LogInterval in ms
Use css_startbenchmark
to start logging data
Use css_stopbenchmark
to stop logging data
The memory and player count data will be stored in /game/csgo/benchmark/benchmark-{currentTime}.json and the frametime data will be handled by VProf in the console log
To graph this data, I created pyBenchChart
