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.

rpm has the concept of %posttrans . Stuff in %posttrans is run after *the entire transaction* has completed, not after *the specific package install* has completed.

However, I think we can't put ldconfig in %posttrans, because what happens if a package installed later relies on the ldconfig being correct for a package installed earlier in the same transaction?

DISCLAIMER: I may be very wrong. Please don't quote me on this.

Seconded =)
