Toon, I would suspect this boost is from the series of changes to "Update default arch for x86" from HJ Lu. This should now have -msse2 in use as the default (except on darwin where we went to -msse3 since all of our processors support that).
That could well be. I now configure as follows: --with-arch-64=native --with-tune-64=native as opposed to: --with-arch-64=core2 --with-tune-64=core2 previously. -- Toon Moene - e-mail: t...@moene.org - phone: +31 346 214290 Saturnushof 14, 3738 XG Maartensdijk, The Netherlands At home: http://moene.org/~toon/ Progress of GNU Fortran: http://gcc.gnu.org/gcc-4.5/changes.html
