This is the difficult point. Actually this is my personal and
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.
