      Description

      It would be a lot more useful if query execution times are reported at a higher accuracy than milliseconds. Measuring in milliseconds in mongo is akin to measuring the 100m sprint in minutes for us . Whether it becomes ms but in floating point or micro/nanoseconds isn't important to me. If you run 40-50k ops per machine per second they're always going to be either 0 or 1 milliseconds (with some hickups here and there) which makes it hard to tweak the system.
