stack commented on HBASE-779:
-----------------------------

In todd lipcon testing, this parameter set to 2 seems to increase rate at which we take on
writes considerably (duh!) and until he hit HBASE-751, all seemed to be running smoothly.

> Currently its set to 1.  Under load, seeing fill-cache/pause-while-cache-is-flushed cycle.
   Changing multiplier to 2 could make hbase take on load faster (Was set to 1 because compactions
used to overwhelm the system but now HBASE-745 added a not-so-dumb compaction algorithim,
we might be able to run w/ a value of 2).
