Mongo oplog vs pollingThrottleMs


#1

I am interested if anyone did some tests on which one is more efficient for scaling. I’ve read than oplog does not scale really well and pollingThrottleMs setting introduced in 1.3 allow for polling control. Lets say I have a chat app with a lot of users and a lot of messages and I increase pollingThrottleMs from 50ms to 200ms, would it be more efficient than oplog?
