* | Improve lock performance when a lot of locks are waiting (#16840) | Mathieu Velten | 2024-03-14 | 1 | -6/+9 |
| | | | | | | | | | | | | When a lot of locks are waiting for a single lock, notifying all locks independently with `call_later` on each release is really costly and incurs some kind of async contention, where the CPU is spinning a lot for not much. The included test is taking around 30s before the change, and 0.5s after. It was found following failing tests with https://github.com/element-hq/synapse/pull/16827. | ||||
