Last time I did that (ca. 2000), I measured a 20-30% > improvement in run-time execution speed. I get that improvement using gcc3 over gcc2 on intel. In fact, gcc these days, on my code, is a bit faster than Intel's compiler. Even on Solaris/sparc, I know many people who prefer gcc to Sun's compilers (perhaps not for speed reasons, but people who want numbercrunching speed don't use sparc any more anyway...) Rahul
