I _don't_ want to speed up a particular program by modifying it, I
want to take a set of existing programs which are treated as black
boxes, and compile them all with the same flags. I don't want to
experiment to see which flags give the best particular result on a per
program basis, or even for the benchmark as a whole, I just want to
know what the "standard recommendation" is for people who want fast
code but not to understand anything.
All this and more on the under-publicised Performance wiki,
http://haskell.org/haskellwiki/Performance
It's a very good resource, and I've read it before :)
Another way to treat my question is, the wiki says "Of course, if a
GHC compiled program runs slower than the same program compiled with
another Haskell compiler, then it's definitely a bug" - in this
sentance what does the command line look like in the GHC compiled
case?
Thanks
Neil
