Importing a CSV file with mongoimport is very slow, processing at around 4 MB/sec.
The database is capable of more than 400 MB/sec. Parsing CSV files should be possible even faster than that. Using multiple threads is not really a solution as it is often desirable to maintain insert order, and it also should be independent of making the single-threaded case perform reasonably well.
