This question has been a mystery for me too; Even if we assume that some people still haven't upgraded to P4 and still use P3, and even^2 if we assume that some people still use P2, and even^3 if we assume that some people still use Pentium1, then why the hell doesn't RH upgrade at least to i586 and still supports i386 ?! I think the reason was written by one of the many people who responded: Some competitors of Intel, such as AMD, don't support some of the recent instructions of Intel, even in their newest precessors. And don't think only about AMD; There is also Transmeta which emulates the instruction set and I'm not sure they emulate the latest instruction-set. There are virtual machines (such as VMware) (although I run Mandrake as a guest, flawlessly). But the real mystery is the amazing results that Diego achieved ON THE SAME COMPUTER; If 386-compiled executables run faster than 586-compiled and 686-compiled, then RH decision is clear and understood, but the amazing results are less understood.
