Well, I had to do it. Install 11.1. At the same time I erased Vista. So just running openSUSE now.
My issue is not zypper or download speed. It’s the GUI for Yast.
Response time in Software Management, when filter by repo, click from one repo to another there is several seconds delay and with Packman about 30 secs, before the repo contents display.
This is a big change from OS 11.0 which was lightning fast.
You are right! The software management tool in 11.0 war really great and fast. Now I sometimes thinks it’s chrashed >:(. Let’s hope for a bug fix ;).

Noooo… Not again! 
See Bugs:Most Annoying Bugs 11.1 - openSUSE - if you follow to the appropriate bug report you will see that there is already a test update available.
Yeah, I see that Update, just had a email from Bugs about it. I’ll give it a go and see.
I can confirm that the test updates do seem to solve the issue. I will report this back to the bugs team.
Update has been release meanwhile.
