Module:Sandbox/Aidan9382/Benchmarker/doc

A module benchmarker aimed at benchmarking at a wider scope and reliably. This differs from the standard MediaWiki Lua Profile in that it profiles specifically exported module functions instead of every function (e.g. standard string library functions). This lets you figure out what module is making expensive calls rather than what expensive calls are being made.

Usage
To benchmark a module and all submodules it calls, put  on the first line and   (or the equivilant to p) at the very bottom just before the return in the highest level module you want to benchmark from. You do not need to include the benchmarker in any other modules.
