I'm not sure if you're going out of your way to be a dick or just obtuse but 1) that's not true on most SSDs, 2) there's overhead with all the indirection on a Digital Ocean droplet, and 3) this is obviously a straight forward user space implementation that's going to have all kinds of scheduler overhead. I'm not sure who it's for but it seems to make some reasonable trades for simplicity.

If it's about making trade-offs for simplicity then use Kafka.

Some poor quality software with bad performance, but an established piece of tech regardless.
