Scaling Playwright Crawler on GCP Cloud Run

Yo everyone. Starting to try and hit my crawler with some real load. Playwright setup in GCP Cloud Run... do you think a tonne of info logs I haven't cleaned up could be impacting performance? If so that's my lowest hanging fruit 😂 Otherwise should I skip to looking at parallelization? What is performance like using lots of average/small/cheap instances versus overprovisioning a single cloud run instance and smacking it with load? Not looked at the internals of crawlee too deeply so hoping the community can save me some time here 🙏

Wow, didn't know this...but: 
console.log calls in nodejs are synchronous(!) and block the event loop. I just experienced that when I logged the results from executing (asynchronous) sql queries with pg. Logging only 20 items and their (few) properties decreased the performance from 3ms to 300ms on my local machine.
