Haha, it's cool. I once had a problem where I needed to scrape a bunch of sites at once, and ended up using it as a benchmark for threads vs asyncio. The overhead with threads was high even when using a handful of threads, and quickly hit a plateau after scaling to 4-8 threads on a 16 core machine. I was a big fan of the concurrent.futures executor model and generally thought it was good performance anyway, but figured I'd try to implement it in asyncio, and rate limited both for a fairer comparison. It was so shockingly fast that it was the last project I reached for threads again with on Python. I can't say that it was an equitable comparison, but it certainly left an impression on me.
