This mirror is too slow:

It's worth a try, it'll go to the mirror admin - that's me :-)
There isn't much we can do about a mirror being "slow". Anton Aylward has brought up the topic too. Most likely it is not the mirror that is slow, but the end-to-end connection.
300 Kb/s when my connection is 100 Mb/s is very slow...
Like I said, you have to consider the end-to-end connection, looking at either end is of little use. I am certain the University of Lissabon has a very decent uplink, and yours is also fine.
Try doing a traceroute, that might give you an indication of the quality of the interconnection between your provider and Uni Lissabon. From my location, I see about 10 hops (ipv4), but the first goes via Milan. The IPv6 route is virtually identical.

Right now I am downloading an ISO from ulisboa.pt - the speed goes up and down quite a bit, but it seems to mostly run between 1 and 2Mb/s. A concurrent download from Nuernberg is running at 25-26Mb/s. A 3rd concurrent download from a Hetzner datacentre is racing along at 40Mb/s.
4Gb ISO download from Uni of Lissabon -
Hetzner @ Falkenstein - 89seconds, 43.3Mb/s. openSUSE, Nuernberg - 3m35, 18Mb/s. Hostsuisse, Switzerland - avg speed 2.34Mb/s.
I think we can conclude (with some guessing) -
Hetzner has a very direct interconnect to Portugal (it does not go via Milan, for instance). openSUSE in Nuernberg isn't so bad, but does go via Frankfurt. For Portugal, Hostsuisse is pretty poor.
The mirror at Uni of Lisboa is not slow. It can easily feed 50-60Mb/sec. I suspect much more locally.
But not to me...
It might be worth mentioning that measuring with wget (as I also did) only gives an indication of one mirror - whereas zypper will use chunked downloading from multiple mirrors, which should give you an overall much better performance.
Yes, but I had to use wget to populate a partial local mirror. Maybe if I could use aria2c instead that would make a difference, but I don't know how.
Feel free to report slow mirrors, but there is very little we (openSUSE) can do.
Not offer them from the Brain. As we can not configure a local file to disable them... -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)
