dpkg is a pathological I/O workload. Suggest you do the install in a
chroot via debootstrap, then copy the resulting filesystem to your SD
card or whatever in one hit. You might also consider setting unsafe-io
in dpkg.cfg (once you understand the implications, of course).
You can also gain a small saving by having dpkg skip documentation and
localization when extracting packages:
printf 'path-exclude %s\n' >>/etc/dpkg/dpkg.cfg \
/usr/share/{doc,info,locale,man,omf,gnome/help}

[Some background for the lurkers...]
r-pi and one other (pre-dove marvell?) are ARMv6.
AFAIK, *ALL* other kit still being produced is ARMv7.
r-pi is the only thing keeping ARMv6 interest alive.
Ubuntu armel targets ARMv7 and does not require an FPU.
Ubuntu armhf targets ARMv7 and requires an FPU ("hard float").
Debian armel targets ARMv4t and does not require an FPU.
Debian armhf targets ARMv7 and requires an FPU.
Debian arm64 targets ARMv8 (64-bit).
Raspbian armhf is Debian 7 recompiled for ARMv6 w/FPU.
Currently Ubuntu armhf and Debian armel are officially supported.
In their next release, Ubuntu drop armel and Debian support armhf.
IMO r-pi is appropriate for the niche market where an arduino isn't
enough, and a beefier armv7 system is too expensive. I recommend buying
ARMv7 -- which board depends on your application, e.g. historically
Marvell Dove is the only one with a SATA controller that wasn't daisy
chained off the USB controller, so it was the obvious choice for a NAS.
