I ran some tests on my Dell Latitude D430, which has ext4 and a ridiculously slo w hard disk. I tested with:
$ echo 3 | sudo tee /proc/sys/vm/drop_caches; sudo dpkg -i /var/cache/apt/archives/openoffice.org-common_1%3a3.2.0-7ubuntu4_all.deb | ts
old dpkg: openoffice.org-common: 56s unpack, 25s config/triggers ubuntu-docs: 25s unpack, 4s config
Colin's PPA dpkg: openoffice.org-common: 23s unpack, 23s config/triggers ubuntu-docs: 23s unpack, 4s config
So it makes quite a difference for the unpacking of openoffice.org-common (2860 files, huge), and not so much for ubuntu-docs (7454 files, smaller)
