Garbage collection in .Net 4.0

Question

Is there any change in .Net 4.0 garbage collector execution?

Answer 1

Yes, lots.

My latest book Visual F# 2010 for Technical Computing includes a lot of performance-related information about .NET 4 as well as F# itself and the performance measurements and advice are quite different with .NET 4 and the new background garbage collector. In many cases we're seeing substantial performance improvements but there are some slowdowns as well.
