.NET 4.0 vs older versions performance comparison

I found something similar discussed, but it was while .NET 4.0 RC. As for current moment does someone tries to do some performance comparison and can share with as.I开发者_运维知识库t is very interesting as besides other changes such core modules like CLR and GC are updated. Does that gives any performance advantage.

Performance is pretty specific to particular scenarios. You cannot simply measure "performance". You have to measure "performance of [detailed, repeatable situation]".

The only real way to answer this is to measure it for your specific code.
