@roshannaik Thanks for the details. I will try and run a similar topology
to see the difference and see if there is something we can do. Do you have any
suggestions on how we can improve the performance of the check in clojure ?

> EventLogging has performance penalty. For a simple speed of light topology
> with a single instances of a spout and a bolt, disabling event logging
> delivers a 7% to 9% perf improvement (with acker count =1)
> Event logging can be enabled when there is need to do debug, but turned off
> by default.
