ChangeLog? 455 (I think) removed the existing hot spot cache mechanism.

Attached to this ticket is a graph showing a drop after when the default hotcache was removed. I mark this ticket as a defect (versus a task or feature) due to this performance regression.

It is useful in case of huge external databases that cannot be loaded into in-memory.

vorner suggested: I think an query-answer cache (with rendered response packets) would make more sense.

I personally think we should clarify requirements, or at the very
least try to gather such information. See #2228.
