GHC does a lot of cross-module inlining already, and *does* write stuff into interface files, provided you use -O.
I used -O4. Is that the bad thing?
I'm always interested in performance differences of a factor of 15 though! Can you supply an example (as small as poss) for us to look at?
Yes certainly, although small will be a big problem, I guess. I admit that the factor 15 is a bit dubious since the fast run-time was so small (1.88 sec vs. 0.112 sec). I will see what I can do on the morrow.
