-------------------------------------

IMO, more regions are better for read, but worse for write

> Supporting large number of small regions can help improve scalability in terms of number
of tables/cfs/etc., help speed up recovery, and also lessen the impact of compactions (due
to there being a large number of small compactions). 
> This is an issue to attempt brainstorming current limitations.
> We might want to take this into consideration when designing master tasks such as in
HBASE-5487.
