Deserializing large result sets slower than the default Mongo Linq provider

[tom1952]

For large result sets, (5000k+ TestDocuments) I'm seeing deserialization of MLPP slower than for the default provider. Hooking up the profiler, the issue appears to be just getting the results of the Aggregation Framework command. Getting those results is using the BsonBaseSerializer whereas the default linq provider is using the BsonClassMapSerializer. Perhaps that's the issue? See the attached screen shot of a profile analysis.

(Moved this issue over from bitbucket)

Note to self: test this again and see if this is still the case given the churn in both the MongoDB driver code and MLPP
