I don't have access to my Debian machine right now, but last time I did ...It took far more than 15 seconds. I assume that I had a lousy mirror.

That would be extremely rare for Ubuntu. Can't comment authoritatively on Debian.

If you disable the fastest mirror (or select the mirror by hand, like I do in Debian), you can shave ~30 seconds of this list.

1:00 to 1:50 still sucks badly. Again, I just leave my mirror settings at default and have never had a need or desire to fuss with mirror optimizing band-aids on any of my Ubuntu boxes anywhere.

I fail to what yum (as product) as to do with lousy mirrors.

Note my liberal use of the qualifier "in the real world". In my rather extensive experience with both Fedora and Ubuntu, Yum on Fedora is slow and clunky compared to Apt on Ubuntu, which typically shines.

BTW, I have a long history (1997 on) with the Red Hat side of the Linux family, and was skeptical that Apt was as great as people claimed. But the difference has been so striking that I am surprised that people actually bother to argue for Yum.

I see that you're using Fedora 8. As you well know, a -lot- of work has been done to improve yum in each release, and Fedora 10 yum's performance are far better than Fedora 8's.

Well, that's the perennial Yum promise. Like a balanced budget by "Now + 8 years" or the classic old Mozilla chant "The latest nightlies are awesome!". Yum has gradually gotten better, yes. (I used FC1, when all the headers were individual, uncompressed file downloads! How could it get any worse?) But based upon experience, I take the semi-annual claims of huge improvements in yum with a large block of salt.

But yes, my Yum experience is ending with F8. The Fedora upgrades, these days, seem to be nightmarish on a server with a complex configuration, so I skipped 9 and 10 to avoid further embarrassment, and am now fielding security updates manually. And my primary focus, at this point, is upon migrating away from Fedora as quickly as practicable.

While I have zero experience with Ubuntu (Its possible that Ubuntu's popularity means it has far more mirrors than Fedora, which in-turn, help apt take the upper hand), most of the problems you see in yum, I see in apt under Debian: Problematic/slow mirrors.
True, apt does have simultaneous download support, but yum offsets this problem by offering better mirror management.

My Debian experience radically differs than your Ubuntu experience. In 4 years, I've seen apt (I'm using -Sid on a number of embedded systems) crash, fail on broken dependencies and get download files at 2KBps. I've seen it all.
So in -my- experience, Debian's apt is no better yum.

A couple of things to consider:
A. Even if Ubuntu's apt is 4 times faster than Fedora 10's yum, IMO, given the pace in which Fedora releases updates, yum is good enough (tm). As the repository cache is routinely being updated in the background, the actual -user- experience is immediate. (I just conducted a search in F10's "Add/remove packages", and got the results immediately)
B. Yum is getter far more development than apt. I have no idea what's the current status of debdelta in Ubuntu, but as far as I know F11 will be the first major distribution to officially offer delta based downloads.

Never the less, I can't (and won't) argue that F10 is a good production server. Nor do I argue that RHEL/CentOS 5.3 is a good desktop solution, as RHEL 6 is greatly overdue.
I am saying that yum, at least in it's Fedora 10 state, is no longer an issue.
