Hmm... I am guessing it bases directory usage to minimize file-lookup time based on the number of items in the cache not (i.e. not size of items),
yes, sort of. The L2 value of 256 is selected to give reasonably sized directories which should have good lookup times and filesystem cache hit ratios on most systems.
and, I may have had large items in my cache so I reached the cache's space limit before it needed to use more level-1 dirs?
May be the case.
There is three condiditons for items to be deleted from the cache:
1. Replaced by a newer object for the same URL
2. Removed by the removal policy to make room for new objects when the cache is full.
3. Expired and not used in quite a while.
