Add rate limiting for analytics

**Feature request**
It would be great to have compression for auth.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_compression` with default `false`.

The title requests analytics rate limiting, while the body describes auth compression and an `enable_compression` option; no files, tests, or entry points are named. First clarify which behavior is intended and where its configuration and authentication or analytics paths live, then define tests and the expected production behavior before implementation.
