Q: 

Speed test Linq2SQL v Entiry Framework

Has anyone compared the speed of performance between LINQ to SQL against the Entity Framework?

I have heard that LINQ to SQL is 4 times faster than the Entity Framework, but I've never seen any bench marks or sample application proving this.

A: 

There's quite a full investigation here, although it is an MSDN blog so potentially biased I suppose.
