Found what the problem was, thought I should report even though it has
nothing to do with Squid. Problem is Broadcom chipset related, TSO
makes it behave at 16K/s when sending IPv6 packets (TX, does not
affect RX). Bug:

Just to be clear, the problem is not on the squid server but on the
IPv6 server (which incidentally, is a kvm server).

So that fixes it: ethtool -K eth0 tso off
