Hi hshutao,
There are various reasons:
The rendering pipeline is being completely overhauled on a branch at the moment - large preformance improvements expected here.
Very little optimization has been done on v2 yet
There is some plumbing for performance enhancing features which are not yet implemented - things like query caching..
Some of the indexing could do with some work 

Also the v1 library is much lighter weight -  far less validation is done on the objects

Hope this clears things up.. jd
