I can't speak for anyone else but myself, but I'm currently running
Sendmail, Apache, Mailman, Qpopper, Mysql, and Samba on a dual 800mhz system
and it's doing just fine on 4.8 and processing approx 25k messages every 24
hours including AV scanning. I've yet to see it fall below 60% idle under
heavy traffic. It normally sits at 86 - 99% idle. So, for me, the smp works
rather well.
