This is "single socket read" histogram. It has little to do with object
sizes. For example, a huge object will have many "entries" in this histogram
bins.

The simplest way is to use cache.log -- it shows both the actual number of
objects in your cache and the swap (cache) size. The size/number ratio is
your actual average object size. Should be somewhere around 10-13KB.

Note that for very small caches, those averages do not work very well; just
because the object size variation is large.
