Entirely possible -- but, if you don't try it, you'll never know... ;-) I thought I'd try, because anecdotal evidence suggested that the optimisations made a performance difference (a positive one, that is). If you have profiled and benchmarked code with no opts and compared it to code compiled with optimisations, I'd be interested to see the results. I mean, if there's no point, I'd like to know so that I can stop wasting time fiddling with these things... ;-) -- Juha To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
