Luke Boswell (Aug 04 2023 at 06:05): Luke Boswell (Aug 04 2023 at 06:05):I'm working on an idea to benchmark the performance of different implementations for processing bytes in pure Roc. My objective is to have something that can give me real feedback for various ideas to speed up json decoding.
What I have so far is relatively simple, but I would appreciate any feedback on ways to improve this. I have never really benchmarked anything before, and I played around with hyperfine and time commands but feel like just timing things from within Roc is probably also acceptable for now. It would be good to know if there are better ways to do this.
Specifically, I'm looking for better ways to time the processing logic. :smile:
My current idea is in this gist and uses this twitter.json benchmark file.
