Or did you benchmark it? Actually, both. In heavy matrix math (with lots of determinants, inversions, etc.), Intel beats GCC by a mile.

The GCC output was so naive it made me wince. --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
