There's the Performance section of the Haskell wiki:


Some of the techniques are described there, but by no means all.  It's a good 
place to put knowledge that you acquire while doing these experiments, though.

FWIW I vaguely recall there was a performance problem with initialising 
IOUArrays that we haven't got around to fixing yet.  If you can narrow down the 
test case, then please submit a bug report.
