I already do that. I have about 30 positions that I use during the profile stage of "make profile"... I'm not sure what the -openmp is supposed to do since I am not using any of the openMP pre-processing directives for parallel programming... By the way, I also use -fno-alias since I don't write that kind of sloppy code... I will try the -O3. Last time I did it slowed down just a bit so I stuck with -O2...
