Elliott Clark commented on HBASE-6730:
--------------------------------------
bq.May I ask how the default of 15 was obtained
It seemed like a good balance between remembering too much (keeping a lot of
objects resident) and remembering only the last one which wasn't useful. Unix
uses 15 mins in it's load metrics so it seemed like a good number to follow.
