Why choose async/await over threads? | Hacker News
Multi-threaded async/await gets ugly. If you have serious compute-bound sections, the model tends to break down, because you’re effectively blocking a thread that you share with others.

At the time of this writing I’m able to index and search the text of around ~17 million memes on a shared Linode instance with only 6 cores […]
