ASP.NET ORM for High Scalable Websites

Question

Which is the best option for High Scalable Websites or Enterprise Applications:

1. LBLGen
2. .NetTiers
3. LinqToSQL
4. NHybernate
5. Repository Pattern (CodePlex)

If any other available let me know.

Answer 1

See ORMBattle.NET - high performance is usually related to scalability. Of course, mainly indirectly: high performance is related to code perfection in general; being really fast implies deep understanding of all the background issues and the ability to deal with them.

Note (or disclaimer): I'm one of persons related to creation of ORMBattle.NET, as well as one of DataObjects.Net authors.

Answer 2

CSLA (http://lhotka.net/) is an excellent Business Object Framework that will definitely scale up to commercial enterprise applications.
