Perhaps we can wait a bit before concluding on this. Some of you feel
confident that there is a minor or no hit based on whatever topology/setup you
have used. Whereas it is quite significant on the one i used.
My current topology is implemented to run within the storm-benchmark tool.
I can rewrite that as a regular topology so you can run it easily to validate..
OR, if you are comfortable running it, i can share it as is more quickly.
> Disable event logging by default

> Fix For: 1.0.0

>
> 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.
> **Update:** with acker=0 the observed impact was much higher... **25%**
> faster when event loggers = 0
