v1.X vs v2.X

Mongodb native driver has been changed a lot in 2.X (doc).

A simple test performs the same operations for each driver: connects to the specified or local db, runs each crud command 1000 times in series within _mongobench collection, reports total duration in ms.

Some common patters data shows

• driver v2 is visibly faster on all basic CRUD queries when journal:false
• driver v2 is visibly slower on inserts with journal:true
• driver v2 is slightly faster on other crud with journal:true

Of course results depend on environment, mogno version, connection strings and somthing else.
