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: https://bugzilla.redhat.com/show_bug.cgi?id=531270 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 Cheers, Steph
