Not d/l speed related. I just want to share. I update a very fast 8 core
server, with a conventional disk drive. Took 2-3 hours, not including d/l.
I update my laptop which has an ssd (and MORE packages). Took 10-15 minutes.
I think this might simply have to do with rpm running ldconfig (a very
disk IO expensive operation) for a large number of packages. I'm not
sure yum/rpm has deferred ldconfig processing.
DISCLAIMER: I may be very wrong. Please don't quote me on this.
ldconfig gets run a lot yes, but its also really fast these days.
fdatasync() which gets called even more (a lot more at that) seems like
a more likely painpoint on upgrades.
