Benchmarking and profiling

Only applicable to packages which contain benchmarks(jest.bench.config.js).

You can run benchmarks with pnpm bench.

Attaching a profiler

Running pnpm bench:profile will launch bench with --inspect-brk flag. Execution will be paused until a debugger is attached, you can read more about node debuggers here

An easy way to profile is:

1. open about://inspect in chrome
2. select which process to connect to(there will probably only be one)
3. go to performance tab
4. press record, this will unpause execution
5. wait for the benches to run
6. finish recording
