Zypper lag?

**camper365** · 29-Dec-2009, 23:20

Whenever I run zypper from a command line (as root) it sits there with no output showing up. After about 2-3 minutes it confirms whether I want to install whatever program I requested, but it takes a long time. Does anyone else have this problem?
I have disabled IPv6 because it causes a lag due to my DNS servers (I have read that Ubuntu Lucid has a fix to this on Launchpad https://bugs.launchpad.net/ubuntu/+s...7?comments=all, I don't know how successful it is) and I am not experiencing a delay on any other program that uses the network.

No I don't get this.
Is the same true in Yast Software Management?

When I start YaST I have to wait while it does an autorefresh and there is a delay when it starts to download files that I don't experience right before I download in zypper, only during program startup. I also don't experience a delay when using cnf

zypper will have lag on auto refresh too - But it just depends when the last refresh was. But you will notice it as it displays in the terminal.
The DNS issues affecting a few users should have been bug fixed and patched via updates.

Nothing at all displays on the terminal when the lag occurs. However, when an autorefresh recently occurred the lag doesn't happen.

I haven't experienced a fix regarding that. I temporarily enabled IPv6 to test whether a fix came or not and I still experience a delay. I click on the updater applet and it tells me no updates available. I click on check and it still tells me that.

That looks good.
Not sure where you go from here

Hi,

I have the same experience here zypper on official repository (and build service) lags but works flawless with VLC repository.

First problem was that IPv6 could not be disabled via yast https://bugzilla.novell.com/show_bug.cgi?id=539869 after solving this issue all other network connections were working as expected but only yast and zypper does still have theses lags on build service and update repositories.

I've searched around and found out that the aria2c backend causes this problem when ara2c is disabled yast and zypper are working without any lags. I've reproduced this behavior on 3 completely different PCs with the same result. Because others don't have this problem it must be related to my router hardware or it is a problem with my ISP and p2p torrent downloads.

Happy new year

This is interesting. I just thought the servers were slow. I also use a high speed satellite connection with lots of lag time. I used

Code:

export ZYPP_ARIA2C=0

and ran

Code:

zypper -vvv ref

and it took half the time to finish. I then read up on zypper and found out it uses aria2 to do it's job. I'm going to do some more testing. What is it about aria2 makes zypper so slow?
