> Are you building with --enable-checking (the default)?
On AMD I am using the François-Xavier's builds. On my G5 I use a patched
version of the Fink's info file, the answer is probably in
ConfigureParams: --prefix=%p/lib/gcc4
--enable-languages=c,c++,fortran,objc,java --infodir='${prefix}/share/info'
--with-gmp=%p --with-included-gettext --host=%m-apple-darwin`uname -r|cut -f1
-d.` `if test ! -f /usr/lib/libSystemStubs.a ; then echo -n
"--with-as=%p/lib/odcctools/bin/as --with-ld=%p/lib/odcctools/bin/ld" ; fi`
and as far as I can tell is "no".
> Can you try compiling some of the most-affected files with -ftime-report, ...?
As a quick answer, with -ftime-report on induct.f90 I get:
[karma] lin/source% time gfortran -ftime-report -O3 -ffast-math -funroll-loops
induct.f90
