I did, however, measure the performance difference on a running system.
1) Install Ubuntu 10.04 Server
2) sudo apt-get update
3) sudo apt-get dist-upgrade --download-only
(32 updates available now)
4) time sudo apt-get dist-upgrade
takes 3m33s
Then:
1) Install Ubuntu 10.04 Server
2) Upgrade dpkg to -proposed
3) sudo apt-get update
4) sudo apt-get dist-upgrade --download-only
(32 updates available now)
5) time sudo apt-get dist-upgrade
takes 1m52s
There's clearly a huge performance improvement. I would like to see this promoted from -proposed to -updates, and would very much like to test this on a real ISO whenever that's available.
10.04.1 candidate images are not yet available.
