I have this at the bottom of my squid conf: delay_pools 1 delay_class 1 2 delay_parameters 1 -1/-1 125000/125000 On connection, it seems each individual client is being limited. However, iftop shows a connection to one site of over 6Mb?! Any ideas on why this is escaping through the throttle?server88-xxx-xxx-198.live-servers.net => iplaydl0.thdo.bbc.co.uk 169Kb 146Kb 124Kb <= 7.11Mb 6.44Mb 5.56Mb
