Think its 686 (but really, leaving 486 and 586 in isn't going to slow down booting or anything!) I always say: Use GENERIC unless you have a good reason
not to.

    Second, is it safe to do a buildworld with -O3?  If there are

No. It's not supported if things break.

    stability concerns, I'll go with the default when I rebuild my
    6.2 systems.

The defaults should be fine. Also, like I said consider just using GENERIC and
load the odd kmod if needed. Generally it's less headache and equal
performance.

    thanks in advance,

Dan,
I know that this has been discussed a few times before, but IMO running a slightly stripped down kernel (i.e. custom, not GENERIC) actually proves to be helpful in increasing boot times (if options were added statically) and compile times if [(# of options added) < (# of options in GENERIC)].
I can confirm this too. I noticed on both desktop and servers the boot time can be decreased by stripping the kernel configuration of stuff you don't need. I don't have any hard facts to prove this but this is what my personal experience is.

I like being able to compile my kernel on my P4 in less than 10 minutes anyhow with less options :). The only thing that was brought up earlier (sometime later last year in a thread--I think either Oct or Nov) is that removing options removes flexibility as well. But that's a tradeoff you have to make.
