If you understand performance as well as you claim to - and from your previous postings, I believe you *do* understand performance well - then you will know that "10-20% speedup" is almost entirely meaningless in isolation.
Any given particular program has a bottleneck; this bottleneck may be
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 -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
