Thanks very much. Just one more question: do I have to change anything when compiling xmonad and xmonad-contrib, or just use those arguments when calling 'xmonad --recompile'?
No, you'll have to compile xmonad by hand (with cabal configure -..flags ; cabal build ; cabal install).

You need to call ghc yourself instead of `xmonad --recompile', once you've built the xmonad library with profiling (as Don outlined). xmonad calls ghc for you with more or less:
ghc --make xmonad.hs -i -ilib -fforce-recomp -v0 -o ~/.xmonad/xmonad-$arch-$os
And `xmonad --recompile' doesn't listen to any additional flags. So you'll have to call ghc yourself, and make sure that you directly run your compiled config with appropriate flags for the RTS.
I wonder: is there any way we can pass additional flags to ghc if we wanted to (say, to enable -O2 or something)? Maybe even pass extra flags to xmonad when restarting it so that we could set up profiling within xmonad itself (though I'm not sure where the resultant profiling output would go... ~/ ?). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
