Spawning from [looking](https://matrix.to/#/!cnVVNLKqgUzNTOFQkz:matrix.org/$XOVFm5mjCzzmhUaGc202zGdSq8eWgjr00MJqNSfzHiA?via=element.io&via=matrix.org&via=one.ems.host) at some traces and seeing the Synapse Rust HTTP client taking way longer than what the Synapse Pro Event Cache claims it was able to respond in (added some [better tracing](https://github.com/element-hq/synapse-pro-modules/pull/38) for that). I don't think this specific change will have a meaningful impact but just something I saw (pre-optimization).
