Some one *please* explain to me why they keep insisting on using something other than "-O"? How much do we need to document that anything above that can be dangerous on FreeBSD.

Have people actually benchmarked their apps and seen a difference in speed, or is it just the "Oh, I need the fastest baddest code I can get" syndrome? -- -- David (obrien@NUXI.com) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
