It's not the renaming that does it.
It's the making new copies of the files.

OK:
I understand the rpm bit. I do not get the 'defrag' bit by making new
copies of the files.

Renaming is an intermediate step required for copying the files to a new
location with the same names.

Then reading the new copies of the files is faster than the old ones.

And this I do not get. Why would that happen?

I guess that how significant this speed increase is, depends on a lot of
factors. But as I'm always on old slow HW everything counts.

It shouldn't. I see at least no reason for it.

Perhaps somebody else can explain what happens. I asume that is
still on ReiserFS or is that already on EXT3 (or fat16?)

The partition in question is ext3.
As an explanation I'm offering that it gathers the pieces of the files
in a new spot on the disk in one place.

This is not FAT so defragmenting should not be a factor. It *could* help
the first time when moving to the centre of the HD, but that will work
only once.

I seriously doubt that moving from the outside to the inside will give
you any noticable speed advantage. My guess is that if you only do the
rpm bit, all should be well.

It's some time ago that I discovered this while looking for reason for
slowing down the package management.

It took me some time again to find where I got this from:
