      As per the flame graph, currently about 4% of the bulkWrite operation thread's time is spent in parsing the bulkWrite request with 1000 insert ops. In contrast, about 1% of an insert operation thread's time is spent parsing a similar insert with 1000 ops.

      The parsing code is auto-generated through IDL so it may be harder to optimize without changing the format of the bulkWrite request altogether.

      See SERVER-76662 for flame graphs.
