Comment(by each):

 > According to this test, hot spot cache improves performance in terms of
 qps about 27%.  Personally, I'm not so sure if the gain is worth the
 additional code complexity.  Next time we wanted to optimize something, we
 should first have a proof that it surely makes substantial improvement.

 Where is the query.txt file that you used as input for this test?  (The
 one I found in the branch only has three lines in it.)

 I did actually benchmark the hotspot cache, using queryperf, at the time I
 was working on it.  I saw QPS improve on the order of 350-400%; I also saw
 that the elapsed time for individual queries dropped on average from 4-8
 milliseconds to less than one.  So your results here are very surprising
 to me.
