Are your libraries compiled with -O2?
I don't know. How can I check?
I just installed ghc-7.0 by "perl boot; configure; make; make install".
(sorry, I missed your reply earlier)
The default build settings use -O2 for the libraries, so your build is
fine. I don't understand the differences between your
-ddump-simpl-stats and mine, but I think we have this particular
performance problem fixed now anyway (I'm right now validating patches
for the 7.0 branch).
Cheers,
Simon
