@alex @lain @graf @n-2-l @mint @Moon Pleroma doesn't cache enough. Like I said the bottleneck is IO. I struggle to get it to use more memory, I tune all the lame VM options and yet it never really caches more. Meanwhile as a functional GC'd VM language Elixir is constantly allocating and throwing away memory. Even Rust isn't perfect since it tends to promote RAII which involves allocating and throwing away memory.

One of the architectural decisions I did in sneedforo was to cache as much data as reasonable in memory. Avoiding queries to the DB. Imagine the insane performance gains Pleroma could have if it actually cached stuff in an intelligent way. Oh, but that's a little complicated, right? What is the states become stale, that could be a problem. Bro, just don't be a soydev and think about it hard.
