Presumably you mean a *producer*. Is that producer publishing the
messages as fast as it can, or is it rate-limited?
And how did you measure the rate?

Large fluctuations in memory are nothing unusual in most

If the producer isn't rate-limited then message backlogs can build up in
various places throughout the system, before they ever get to the
persister. Furthermore, unless you use transactions, messages are
persisted asynchronously. So consequently you may have many more
messages in memory than have been written to disk.
