I was wondering if codspeed can show both JS stack and rust stack at the same time. If so, we can just port benchmark tests to JS instead of relying on porting JavaScript default value logic to the rust side.

@h-a-n-a My goal is to find a way that can accurately bench the JS API

Hey @SyMind, it seems you are uploading multiple times per workflow, but CodSpeed does not support multiple uploads yet, so you have to ensure that you only call the CodSpeedHQ/Action once per workflow, across all jobs.

In your case, if you want to have both js and rust benchmarks, you would need to run them both in the unique call to the action, something along those lines:

run: |
  cargo codspeed bench
  pnpm bench:ci

The support for matrices and multi-part upload is in the works.
