Disabling IPv6 entirely would involve something more like: echo "GRUB_CMDLINE_LINUX='ipv6.disable=1'" >> /etc/default/grub If a machine has both IPv4 and IPv6 networking available, then prioritizing IPv4 or 6-in-4 over IPv6 is very likely to improve timekeeping performance. (I've seen a few counterexamples where IPv6 worked better, but that is rare.)
