(Get the code!)
I have the same problem, system slowdown and a very long updates. I have the measurement for speed-dreams package 1.4.0 installed from command line (sudo dpkg -i speed*) for Ubuntu 9.10 and 10.04. Both installations are on the same machine, same HD (different partitions, ext4 for 10.04, ext3 fot 9.10), and speed-dreams files (~320MB) are on a another HD. Results for unpacking phase are:
9.10 : 9s
10.04 : 36s
which is way more than two times slowdown...
If it is acceptable by Colin Watson, could there be at least an opton of choosing should fsyncs be done new or old way? I.e. dpkg --nofysync or something?
