Re: Good idea or Bad idea?
-fomit-frame-pointer IS EVIL. Do not use it. portupgrade won't build
with it, cause ruby hates -fomit-frame-pointer. I would just do a
fresh binary install. 6.0 is quite an amazing release... The speed
is remarkable. My machine goes way faster than it did before.
I am using the following CFLAGS successfully with xorg and XFCE4:
CFLAGS=-O2 -pipe -ffast-math
CPUTYPE=p4
I can't speak to building FreeBSD from source. I build all my ports
from source, but didn't bother building the world from source...

(linuxfromscratch.org) and I have learned that sometimes it's just a better
idea to use binary packages (i.e. building everything from source can be
a waste of time if there is no performance gain, and it's easy to screw up.)
I have no trouble following docs, so I'm not really worried about blowing
everything up in the process (even though I might haha...) I'm just wondering
if there are any real (noticeable) performance increases if I build my kernel
and base system from source. Of course either way my ports will be compiled.
Any feedback is appreciated - especially in regards to {C,XX}FLAGS and even
more appreciated in the case of DO NOT USE -br34k-all when compiling __ ;)
I've had my share of oops I guess didn't like -fomit-frame-pointer in
the past with linux ;)
Thanks!

I would imagine that there is some very minor perfomance benefit in that my new kernel and all its bits and pieces is 22mb smaller than the default shipped in RELENG_6 18M./kernel 42M./kernel.old Smaller kernel size is plus, and staying up to date with the latest patches is also a benefit that I hadn't considered. Are there security patches for 6.0 already? I just noticed so many mails on this list recently re: build failures that I thought it would be good to ask if there really was any noticeable performance increase. I know that the OpenBSD project actually discourages users from building the system unless it is absolutely necessary, noting that it's more likely to cause problems than to provide any tangible benefits. So far it looks like a worthwhile venture :) I'd certainly like to see if there are any differences in terms of speed between the default binary build (which for me is i386, and interestingly enough is still called i386 even though 386 itself is no longer supported as of 6.0) and a build done with march=686. It looks as though either way the upgrade to 6.0 should leave me with a system that feels faster. I'd like to wait till the Saturday but I'm not sure how much longer I can fight off the urge to start the minute I get home hehe Thanks to all who replied!

Of course either way my ports will be compiled. I think there is, but I end my optimizations at setting the CPUTYPE variable in /etc/make.conf.
