Every time I post something that gets lots of engagement, I essentially end up carrying out a denial of service attack on myself. What does this say about the design of Mastodon and ActivityPub and the future of the fediverse?
Yes probably. But what each of these jobs is doing is essentially just creating a cryptographic signature and making an HTTP Post request. So its very fast and jobs can easily be run in parallel. Any modern computer should be able to do this thousands of times per second without a problem.
I have absolutely no expertise in this area but could it be explained by the fact that Rust is (potentially) much faster than Ruby?
