What is the performance impact of using Morphia as opposed to directly using MongoDB Java driver?

[zee]

I like the way Morphia maps Java classes to MondoDB documents but I am
not sure about the performance impact.
In application which involves very frequent updates to collections in
MongoDB such as in a gaming application, what is the performance
impact of using Morphia vs directly using java driver?

Does it make a difference if the models classes and application code
is in Scala?

Its been awhile, but you can read the following 2 things:

http://groups.google.com/group/morphia/browse_thread/thread/906085d88dd92915

Might be even better now.

The net net is the impact of morphia should be negligible compared to
the overhead of queries in mongo itself, the network or other parts of
the application.

Also their follow up post confirming the same...
