The "general" package won't get you help from the people who actually know about IPv6 issues. I'm by no means an expert, so please take this advice as it is, it's not necessarily specific to your problem. The most likely explanation for what you are seeing is that there is a problem with your local network. We can't really help you with that. One known source source of slowdowns with misconfigured IPv6 setups is slow name resolution, which slows down making a connection: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/313218 https://bugzilla.redhat.com/show_bug.cgi?id=459756 However, in your case this is probably not applicable; the above won't affect the speed of a connection once established. Are your IPv4 and IPv6 connections of the same speed? If not, and the v6 connection is tunnelled, throttling at the tunnel endpoint might be an issue. I've certainly had fairly slow/unresponsive connections at times due to this. If it's geninely a problem with networking on Linux, I think you should get in touch with the linux-kernel folks. The netdev list at vger.kernel.org might be a good place to start. Regards, Roger -- .''`.
