Description
This issue has been migrated from [#6260](https://github.com/matrix-org/synapse/issues/6260).
---
It reliably uses 5-10x more DB time than any other servlet (presumably due to push action updates?) despite quite a common and boring servlet. i asked erik and he said "yeah, can probably be improved", so filing a bug to that end.
(it's the purple line on the synapse master)
