well, fwiw, adding the sse flags, an -o3 and removing -g gave me about a 33% inprovement in cpu usage. and denormals *seem* to be gone, but this was a brief test. will test more and let you know. thanks for the help!
well, this is no big surprise ... the sse unit is _far_ better handling denormals than the fpu is ... even without hardware DAZ
