Maybe it would not be a bad idea to check the number of cache misses,
branch mispredictions etc. per instruction executed for the shootout
apps, in different languages, and of course, in haskell, on the
platforms ghc targets. Do you think it might potentially be
interesting to the GHC developing community to have such an overview?
It might show potential bottlenecks, I think.
