speed and size of compiled Haskell code

[Jan Brosius]

Hi,

I wonder if someone could tell me more about the speed and size of compiled
Haskell code.
E.g. if one uses GHC to compile Haskell code into native code what speed
performance can be expected versus a same program written in C (Hints about
the nhc compiler are welcome).
Is lazyness as good as strictness.
What about Haskell 98 versus (I anticipate) Haskell 2

Thanks
