My bad I should not be so cynical. Actually mines pretty okay, taking the HUB3 out of the equation, but not as sweet as yours.
Whats changed with you? Network upgrades? Just lucky?
It all changed a few weeks back when my connection dropped and then the hub (SH2ac in modem mode) rebooted itself and I was given, for the first time ever, a new WAN IP. All the evening over-utilisation has disappeared and ... well you can see for yourself. I can only assume that I have been re-routed to a high performing segment of the network.
