Unbounded increases in GC time #7176
Description
Description
After updating to 1.12.0, average event send times have gone up. Metrics are showing GC time going up a lot more than before, around 1 second per day. Memory usage hasn't changed significantly though. @lub:imninja.net's metrics showed the same problem when I asked in #synapse:matrix.org.
The problem did not happen with the 1.12 release candidate, which leads me to believe it could have something to do with the Twisted update.
Version information
- Version: 1.12.0 (https://mau.dev/maunium/synapse)
- Install method: Docker
- Platform: buster-slim, tested both with and without jemalloc
