"MongoDB will create collections and databases implicitly upon their first use: you do not need to create the database or collection before inserting data."

Look closely at Fri May 31 03:10:53.198 through Fri May 31 03:10:55.837 All of that work being done, time being spent, those 2+ seconds, is MongoDB performing initial setup creating the collection required to store the first document I'm adding to that collection.

So: Although "you do not need to create the database or collection before inserting data" you do need to expect that the very first document you add will include a few seconds of setup time.
