No, I'm not syncing portage every hour. Thanks for the info.

I forgot about app-portage/getdelta and friends (mainly because I
haven't used it.) It doesn't use websync, but like websync, it's
supposed to make upgrading faster because only package differences are
downloaded if you add  

        FETCHCOMMAND="/usr/bin/getdelta.sh \${URI}"
        
to your /etc/make.conf. I don't think deltup will help syncing.
