[snip] I would argue that any effort put toward documenting this is better spent documenting something else. That particular "flotilla" of options relates entirely to a group of rather old, rather slow, and rather rare processors. The incidence of their use or necessity in the general FreeBSD user base is likely to be quite small. If you're running on asome ancient bastard child of Cyrix processor then chances are you're not running a performance critical application. At that level I say to anyone who tries to squeeze every last ounce of performance out of their CPU, "buy a faster CPU or UTFSL". Feel free to disagree and work on what interests you. Brandon D.
