At least once or twice a month I'm downloading something and will find the IPv4 to transfer significantly faster. Case in point, I downloaded the proxmox iso yesterday to a colo server with 50g uplinks. It loafed at 2.4 mbytes/s using default wget, which of course preferred ipv6. Adding -4 to wget made that shoot up to 80 mbytes/s.
Have you checked packet loss and latency? Maybe that is caused by different routes due to peering. -- kind regards Marco Send spam to abfall1764603853@stinkedores.dorfdsl.de
