> Currently, we can't determine how many hot (touched recently) and cold pages we have in the page-memory. This information can be helpful for data region size tuning and can show the effectiveness of the page replacement algorithm.
> Such information can be represented as a histogram showing the count of pages last touched in each time interval.
