@mewmew we have probably 3.5k users. Although the number of rooms you are in matters more than user count, you could run into issues after a few hundred users in theory.

Uses around 40-50GB of the 64GB RAM allocated. Constantly pins the CPU on a Ryzen 9 3900 because it’s a single threaded Python app (although setting up Synapse workers helps dramatically, each individual worker will still hit 100% often). Disk usage is around 750GB, more than half of which is just the database, not even media.
