FSE and Poast keep as much in RAM as possible. I haven't checked how well it's played out but Poast's DB server now has enough RAM to hold the entire DB. If I have a look right now, Postgres is using 120GB of RAM on that box and about 400GB are dedicated to FS cache (so probably also Postgres).
FSE is doing similar; we had Postgres using about 90GB of RAM on the old machine, though the new one is smaller.
