 Description   

I have post this question to google groups, please lookup at: https://groups.google.com/forum/#!topic/mongodb-go-driver/NwDvu18faG0

  1. the latency increasing while more goroutine are used(from 1 to 8)
  2. while I use mongo-cxx-driver to run the test, the latency is stable and low
  3. while I use mgo, the latency increases too, but the latency is much lower than mongo-go-driver

This ticket was filed before the core performance improvements.

stutiredboy@gmail.com we're focused on rewriting the core API and getting to MongoDB 4.2 compatibility, so we're deferring investigation of performance reports like this for now, but will return to investigate at a later date.
