You could start by creating a benchmark framework to identify if there
are any significant differences.   Without measurements we are merely
left with speculations.

Recently there was an article in one of the performance blogs that
compared GCC and LLVM on various workloads.   It was better in a couple
of areas and worse in many others.   

There is no clear winner here, and since most Mono could will be
managed, I do not believe we will get much bang for the buck.
