Hi,
There is actually several questions in your e-mail, even though you
really only end up with 1. But here are some of the hidden questions,
leading up to the answer to the one question.
Is yum sometimes slow?
Yes, it can be. This is being worked on. The developers are looking at
both the grand scheme, as well as breaking things down and looking at
function by function. Trust me, they really are concerned and are
working on this. There are so many details I can't even begin to start,
so I guess I won't.
Does yum always take over half an hour with a good network connection?
No, not usually.
If you are on fedora core 6 and do a "yum update" I'd be very surprised
if it took more than 5 minutes. And after you've done it once, it is
usually on the order of 30 seconds.
You stated that your Ubuntu only took 5 seconds to get the output of the
packages to install. That is probably because you aren't running on a
fresh batch of data from the servers. apt tends to cache their data
much longer. Last time I used apt, I had to tell it specifically to go
look at the repositories.
Why is yum taking so long to update from fc6 to rawhide?
That is probably because there are some major dependencies going on.
rawhide may or may not even be yum'able from fc6.
So, to really answer your question, I'll let you answer the question.
Instead of doing a
yum update
do a
yum -d6 update
And then you can see what dependencies it's working on.
Hope this helped somewhat.

I am currently Trying to upgrade from fc6 to rawhide. the "dep
solving" part before you get the nice list of packages to be updated
has taken me over half an hour (at this time it's still going). My
install was made using the live-cd installer made by david z. (very
basic, no OOo or anything major besides gnome). The only packages I
added to this were rhgb and madwifi (if I recall correctly). Why ist
his update taking so long? (I understand it's a pretty big jump but
still..)
On my Ubuntu partiont which I had for many many months with many
packages installed took no more than 5 seconds to give me the output
of packages to install.
I really like the yum tool and I have been watching this list, and it
seems that plans exsist for switching the yum database, will this
improve the dep-solving speed? From my experiance using yum (fc4-fc6)
the slowest aspect seems to be the dep-solving. I know this has many
issues involved with it, but internet speed *should not* be an aspect
here. My connection is 1.5mbps (usually downloads from fedora serevers
go at ~ 130kps not the greatest speeds, but still very acceptable.
What is it about dep-solving in yum that makes it take so long, and
what ways/plans exsist to improve this?
