Microsoft claims that the .Net 3.5 framework has many speed improvements over 2.0. Is anyone able to verify this claim?
I am especially interested in computational type stuff (math, graphics, etc), but also more generally?
The 3.5 CLR does seem to be faster for certain tasks.
Here’s a fairly simple comparison of sorting differences on 2.0 vs 3.5, showing decent performance improvements in .Net 3.5.

What exactly caused the improvements is unclear, but structs were not well handled under 2.0 and inlining has improved in 3.5, both of which can make a big difference under the right circumstances.
