noI'm sure this has come up often, but I thought I'd ask it anyway....
Is there a real performance difference between using a simple, generic i686 mcpu flag as opposed to the pentium4 march/mcpu flag?
For reference, my system is a pentium 4 (obviously) with 1GB RAM. I use it pretty much for:
Internet surfing
Downloadingno
Ripping CD's (hopefully soon to rip DVD's)yes
Watching videos (mplayer)yes
Listening to music (xmms)yes
Some programming (small C++, PERL scripts, maybe some JAVA)no
Running a personal web server (apache)no
MySQL (for the webserver ... again, personal)no
I DON'T really use it for gaming.
where "no" means no changes "yes" means things can go better, "yes" doesn't mean that things will be perceptual better.
Any thoughts?

P.S.: Also, is there difference between using the mcpu vs. march flag?
don't remember but man gcc /march explain this -- gentoo-user@gentoo.org mailing list
