Roger, I'm glad you posted this statement. I've worked in the 64-bit world for over 10 years (Digital Alpha, PA-RISC, IA64, X86-64), and there is some code that certainly performs better in 32-bit mode, not only on X86-64, but in the other platforms. In 64-bit, you not only have more registers, but memory addresses are 64-bit, so executables and libraries take more space, and context switches require saving more registers. -- Jerry Feldman <gaf@xxxxxxx> Boston Linux and Unix PGP key id: 537C5846 PGP Key fingerprint: 3D1B 8377 A3C0 A5F2 ECBB CA3B 4607 4319 537C 5846 -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
