title: MongoDb - Utilizing multi CPU server for a write heavy application
body: <p>I am currently evaluating MongoDb for our write heavy application...</p>
  
  <p>Currently MongoDb uses single thread for write operation and also uses global lock whenever it is doing the write... Is it possible to exploit multiple CPU on a multi-CPU server to get better write performance? What are your workaround for global write lock?  </p>
