@lchanouha I'm guessing the spiky part of the graph from 2022-03-02 to 2022-03-08 is Synapse 1.53/1.54? Which version of Synapse were you running from 2022-03-13 onwards / what changed between...

It's interesting to see that matrix.org's memory usage also shows a linear rise in memory over time, until restarted:  That's like to just be caches filling up though. We...

> Are all of matrix.org's cache's configured with time-based expiry? I think so?

There appear to be three caches that are not subject to time-based expiry in Synapse: * `get_users_in_room`, with a base size of 100,000. * `get_rooms_for_user_with_stream_ordering`, with a base size of...

\> Our issue doesn't look related to cache, the cache usage is consistently very low. `synapse_util_caches_cache_size_bytes` has a label for each individual cache. Does that chart show the sum over...

@felixdoerre Would you be willing to turn on `track_memory_usage` (see https://github.com/matrix-org/synapse/issues/12160#issuecomment-1097993084 for instructions) and get a chart of `synapse_util_caches_cache_size_bytes` instead? It'd be very useful to see the largest caches by...
