Hi Kevin,

You could also look into using a community tool like Flashback 
(https://github.com/ParsePlatform/flashback
<https://github.com/ParsePlatform/flashback>, which captures and replays 
MongoDB workload.

I should have specified that I used Flashback to do this. I had also 
mentioned that I am sending *prod like* traffic, but with Flashback, I am 
sending the *actual prod traffic* to this hidden node. My workload is read 
heavy, so 90% of my traffic is reads and using secondary preference I am 
sending all that traffic to secondaries. And via Flashback, that same 
traffic gets replayed on 3.0 node.

With that information, do you still think that this "load testing" is 
creating a resource contention?

Thanks.
