Pic related is the CPU load on my server has changed --- the spike in the middle was where I had to compile OCaml. Anything before the spike was from running pleroma, and CPU load after the spike is from OCamlot. Seems like there has been a performance improvement.

Bear in mind that the pleroma server I was running was just for testing, had only a few users, and wasn't federating with any other servers.

Will be interesting to see how the behaviour changes as my server starts interacting with other AP servers.
