This is the difficult point. Actually this is my personal and subjective impression. I can explain what I would like to do: As a typical FreeBSD "user" (probably opposed to a "developer"), I do upgrade base system and ports about once a week. In the meantime I have got my work to do (usually with firefox, openoffice, evince, gimp and diverse mathematics tools - all inside my gnome enviroment). Thus I don't care to much about upgrade performance - it should just run in the background and get ready some day. But honestly, I have no idea how to quantify or benchmark this.
