that's good when we consider optimization of specific program, in my
own one bottlenecks are studied and rewritten either in C or low-level
Haskell

but when we say about compiler speed, we are forced to sau about some
average values. these numbers are given by GHC developers, i seen the
same on one test of my own, several bottlenecks fixed can't say too
much good things about ghc - it's not that now we are 100x fatser than
C at least sometimes, it's what we have fioxed some cases when we was
100x slower
