    Description

      There are a couple possible approaches to take here:

      1. add a user configurable knob (pros: easy and easily tunable; cons: easy to misuse)
      2. do an adaptive solution (pros: just works; cons: tricky to get right)

      Other considerations:

      1. It will be easy to overload the server
      2. Need to change how users throttle writes
      3. If it is a requirement that the import is sequential according to the source file, parallel import is not possible

      Because mongoimport works against a single collection, it is the easiest tool to parallelize. Simply read-ahead from the source into memory and use >1 connection to the server.
