Performance and Profiling of the WASM plugin

[maleck13]

What

The WASM module is in the critical data path, It is important we are able to understand how much time is spent in the WASM module and where that time is spent so that we can see bottle necks and identify areas that need optimisation and improvement

How

Export metrics that allow us to profile WASM module and analyse the code performance.
Execute Load tests and observe performance from the profiling metrics
Document the results and how to rerun these tests
