Jonathan Ellis commented on CASSANDRA-174:
------------------------------------------
Thinking about it some more, I think our rule of thumb should be to only add
this boilerplate to debug lines that are going to add overhead on the
read/write path. No sense in cluttering things up with the extra If when it
only executes once in a blue moon.
I'll apply the patch with that change.

> Logging overhead dominates workload for small column values. This can be
> mitigated by switching to INFO but you still have the overhead of throwing
> all those strings together. Some ideas here:
