This is fedora we are talking about.  If you stay up to date you've
replaced almost everything several times and the files are likely
scattered all over the disk.

It is the disk head movement that that takes thousands of times
longer than any other computer operation.  Using separate partitions
only helps in this respect to the extent that they are on
different drives so the heads are independent.  The thing
that really saves you is the RAM cache so frequently used
items don't need to repeat the seek.
