Changing mirror

I have a problem that my updates from are very slow and often fail. I have also noticed that my downloads from (packman) comes very fast.
I would like to alter my mirror.
Is there an automatic way to to this, or does each repository have to be done individually?


Use Yast to add/change the repositories:

Yast -> Software -> Software Repositories

Here you have a list of mirrors:
