Right now, the testcase in comment 1 still is 20% slower ifort/gcc. This is, however, with gfortran 4.3.0. Furthermore, it matters on which CPU you run this (in particular Intel vs. AMD). To summarize:processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz stepping : 6 ifort (IFORT) 9.1 20060707 Kernel time 3.812238 gcc version 4.3.0 (GCC) Kernel time 4.5482836 I'll try to build trunk on this machine and test again, but it might not be for today. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31021
