I've just done with performance test, and the result is a bit different
what I expected.

This patch affects the performance even though event logger is set to 0
thought I can't understand the result.
This performance test is done with your topology + modification for logging
performance.

I restarted all Storm processes for every test.

Since test is done with my dev. machine (MBP), I really would like to
borrow a dedicated machine and try this performance test again.
