Hi Emilio!
Looked through qdist, if I understand correctly, it saves each added (with
different value) element. It is not effective for disk io timing - we'll
have too much

Hi Emilio!
Looked through qdist, if I understand correctly, it saves each added
(with different value) element. It is not effective for disk io timing -
we'll have too much elements. In my approach, histogram don't grow, it
initially have several ranges and counts hits to each range.
