Dear Mirror hosts, Based on your reports I've been investigating the issues with IPv6 performance of stage.opensuse.org vs IPv4 I've been trying to confirm that we do have a problem with IPv6 specifically We know our bandwidth to stage.opensuse.org is suboptimal at the moment (6 days to go until we expect that to be alleviated) but in three sample sizes of ~5 minutes each during periods where our link seemed to be comfortable I've been able to come up with the current results IPv6 - 7.77MB/s | 14.41MB/s | 19.25MB/s IPv4 - 6.09MB/s | 10.09MB/s | 6.52MB/s This is from my personal host (rootco.de) hosted at hetzner These tests were conducted with the default recommended rsync string for all of our stage.o.o mirrors, with the addition of -4 for IPv4, -6 for IPv6, and --info=progress2 to get the average bandwidth calculation out of rsync. The general conclusion - At time of writing I can find no evidence that IPv6 is consistently worse than IPv4 for stage.o.o. It might even be better, though I'd want more thorough testing before making such claims. Obviously, I still think there is scope for different results from different hosts. Peering in particular could be different for IPv4 vs IPv6. If you notice different performance profiles for IPv4 vs IPv6 please report your findings, including source IP addresses and traceroutes. This information will be especially useful after March 1st, when we expect our routing to be significantly different than today. At time of writing, I can see no sign that anything needs to be changed on stage.opensuse.org or anything after the last hop. If the reported problems originate from congestion or peering, the changes to our link expected on March 1st will hopefully resolve them all, and if not we'll have to investigate and resolve with our new arrangements from then.
