You may want to take a look at
Sharding : http://www.mongodb.org/display/DOCS/Sharding+Introduction
Replication : http://www.mongodb.org/display/DOCS/Replication
As well, what is real bottleneck? Is it Web/App Server or mongodb or both?

Hi Raxit!
The first step in fixing your performance problem is figuring out where the performance problem is.
You will need to provide additional information. The best way to do that is to put your MongoDB system into MMS. See here for details:
Once you've done that, if you post a link to your MMS page, I can take a further look at it.
Good luck!
-William
