Description Christopher Brown 2005-08-29 16:07:40 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b3) Gecko/20050827 Fedora/1.1-0.2.8.deerpark.alpha2 Firefox/1.0+

Description of problem:
When Yum is run it takes roughly one minute per repository to set up. This is running yum-2.4.0-1 from rawhide 20050829.

Version-Release number of selected component (if applicable):
kernel-2.6.12-1.1519_FC5

How reproducible:
Always

Steps to Reproduce:
1. Run command "sudo yum update" from shell.
2. Note length of time to get and process data.

Actual Results:  Yum runs but takes about four minutes in all to check for updates.

Expected Results:  Nice and fast grabbing of repodata and processing with expected result depending on whether packages exist that need updating.

I'm betting you have a failing name server and/or ipv6 name resolution going on
when it shouldn't be.

try disabling ipv6 support as described here:
http://www.fedorafaq.org/fc2/#mozillaipv6

and see if it all speeds up.

Comment 2 Christopher Brown 2005-08-30 18:20:51 UTC

Disabling ipv6 doesnt help and even if it did, it would just be another bug.
Workarounds are called as such because they do not resolve the underlying problem.

Comment 3 Christopher Brown 2005-08-30 18:28:16 UTC

...however you are spot on with regards to the failing name server. Is this an
error on my part and yum should not have to cope with dns that do not
exist/respond.....?

Comment 4 Seth Vidal 2005-08-30 22:59:35 UTC

the disabling ipv6 question wasn't about a workaround - but it would be another
bug filed against python, not yum. That's why I asked.

If your network card were flaking out and you were getting a slow connection
would that be yum's responsibility to know that?

no.

it can't be.
