NHibernate proxy class, what should I choose?

What proxy class is best?

1. NHibernate.ByteCode.LinFu.ProxyFactoryFactory
2. NHibernate.ByteCode.Castle.ProxyFactoryFactory
3. NHibernate.ByteCode.Spring.ProxyF开发者_如何学CactoryFactory

I've already used #1 & #2 and they behave equally apparently, no differences detected.

Extracted from nhforge.org blog:

We are using LinFu without a special reason even if I have the impression that LinFu give us a very little performance improvement. For who are using NHibernate without an IoC framework LinFu.DynamicProxy is more than enough.

For who are working with Castle.ActiveRecord and/or Castle.Windsor, obviously, the best choice is Castle.DynamicProxy2 (mean NHibernate.ByteCode.Castle.ProxyFactoryFactory).
