Hmm. I don't have any personal experience with this, but from what I 
read, this idea with CIL is to split the normal compile procedure that does
(1) code analysis, high level optimizing and creating an intermediate 
code that is independent of the original language and the target CPU     
and
(2) low level optimization and target code generation

and perform the second step on the target system when loading.

So it does not _need_ do run slower (it _needs_ to load slower, though). 
But of course a really good "full" compiler might do a better optimizing 
job.

Regarding code snippets that are worth to be done in parallel (e.g. 
calculating a cell in a Matrix Multiplication) should not be highly 
prone to speed degradation by CIL.

I doubt that this is the case :) .
