The problem that I have is that Gmail is utterly slow in IMAP (evolution, thunderbird, etc...) on my computer unless if I disable ipv6. I had a hard time to figuring it out ! Disabling ipv6 in NetworkManager should be enough I think but that don't change anything. If I'm wrong I will be happy to have an explanation but for now I think it's a bug. I opened an issue upstream: https://bugzilla.gnome.org/show_bug.cgi?id=769459 I found the way you said to completely disable the ipv6 but I also found this way that I use: /etc/default/grub GRUB_CMDLINE_LINUX="... ipv6.disable=1" Thank you ! -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
