      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?
      3. Which versions of the driver/connector does this apply to?

      The driver doesn't perform as well as other comparable drivers in a benchmark related to overall throughput. It doesn't appear that individual operations are slower as noted by other benchmarks, but a general slowness when under a heavy load of concurrent operations over an extended period of time.

      Original

      @MongoDB Europe16 John Page talked about the performance of all the different drivers in different languages.

      It was observed out the C# driver was significantly slower than it should be, since you would expect it to be in the same league as the Java driver (and it is a factor of X slower).

      The result was similar in .NET 4.6 and .NET Core.

      So I'm creating this issue to help keep track of what can be done to "fix" this apparent problem/bug.
