Durable consensus means this is waiting for confirmed write to disk on a majority of nodes, it will always be much slower than the time it takes a NIC to put bits on the wire. That's the price of durability until someone figures out a more efficient way.
A NVMe disk write is 20 microseconds.
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.
