Which .NET Relation Mapper is the fastest?

Question

I want to use the Object Relational Mapper (ORM) tool for my ASP.NET application. I have three options: NHibernate , LINQ to SQL, and Subsonic . Which one is the fastest?

Answer 1

See ORMBattle.NET , but pay attention to the description of performance tests.

After spending some time studying the FAQ , it is also highly recommended.

Short answer: among these 3, LINQ to SQL is a definite leader in reading, and NHibernate is in writing. IMHO Subsonic is not the best choice from anywhere (poor LINQ, poor performance).

Answer 2

What about these questions? Subsonic Vs NHibernate and What are the differences and pros and cons of these ORM tools / technologies? . p>

Answer 6

From comparisons and subject to documentation and support, LinqConnect will be the winner. However, this is a commercial production, which may be good or bad depending on your point of view.

Answer 7

I used NHibernate a bit and I think it is a bit complicated. If nothing develops in Java, I try not to use this ORM.
