Dear All,

I am new to ORM tools (nHibernate) and my question is "Is fluent Hibernate is suitable for Large Scale Applications"?
I asked the because it read it has performance Issues (i read on its disadvantage list).

What i mean "large scale applications" is
* If no of simultaneous access of an applications (1000 or 10000 or above users access a same web application simultaneous)
* If the Application has huge number of tables & complicated sql queries.
* ex: facebook.com, gmail.com etc.

How is nHibernate's performance on the above criteria?

Please Note: i am going to use ASP.net MVC 3, Mysql 5.1 or Sql Server 2008

Thanks in advance
