Both spinning disks? No SSD's involved? On the upgrade it will have to read the packages from disk and then write them back to the same disk at a different location as files, this will cause a lot of extra seeking (maybe 2x slower here) The laptop drive may be a lower RPM than the other machine disk (if 7200rpm) that would result in 1.5x at least. You have 2.5x the packages, 2.5x if none of those packages are the larger packages, which the stuff you installed afterward may be. Given you have 2.5x the package there may be a lot of stuff you aren't using. On the upgrade you also have to delete the current packages after you install the newer one, another 2x there. So that is 2.5x2x2 ignoring the hard disk speed, that is about 10x slower for the upgrade. >From my experience most of the time is disk io and seeks, very little of it is actaully cpu. My machines will do an upgrade in about 60 minutes, and that is with all of them having SSD's, so I would expect it to be much longer with a spinning disk, 14x does not sound that unreasonable if you have a lot of packages, and a slow laptop HD.
