14	  This option causes statistical information to be gathered on local
15	  caching and exported through file:

19	  The gathering of statistics adds a certain amount of overhead to
20	  execution as there are a quite a few stats gathered, and on a
21	  multi-CPU system these may be on cachelines that keep bouncing
22	  between CPUs.  On the other hand, the stats are very useful for
23	  debugging purposes.  Saying 'Y' here is recommended.
