## Problem We recently added slow GetPage request logging. However, this unintentionally included the flush time when logging (which we already have separate logging for). It also logs at WARN level, which is a bit aggressive since we see this fire quite frequently. Follows https://github.com/neondatabase/neon/pull/10906. ## Summary of changes * Only log the request execution time, not the flush time. * Extract a `pagestream_dispatch_batched_message()` helper. * Rename `warn_slow()` to `log_slow()` and downgrade to INFO.
