@ -1137,8 +1137,8 @@ Caching can be configured through the following sub-options:
* `sync_response_cache_duration`: Controls how long the results of a /sync request are
cached for after a successful response is returned. A higher duration can help clients
with intermittent connections, at the cost of higher memory usage.
By default, this is zero, which means that sync responses are not cached
at all.
A value of zero means that sync responses are not cached.
Defaults to 2m.
* `cache_autotuning` and its sub-options `max_cache_memory_usage`, `target_cache_memory_usage`, and
`min_cache_ttl` work in conjunction with each other to maintain a balance between cache memory
usage and cache entry availability. You must be using [jemalloc](https://github.com/matrix-org/synapse#help-synapse-is-slow-and-eats-all-my-ramcpu)
