Measure request time in Mongo

Answer 1

The easiest way is to set the profiling level in MongoDB: https://docs.mongodb.org/manual/tutorial/manage-the-database-profiler/

As soon as you do this, information about all your requests will be recorded in the system profile table.

Answer 2

.explain("executionStats") .
