Wow, thats some stats there

A bit more impressive than my DUMeter reading setup !
I can understand that if you are pulling in a cached file from one of the proxies, then you will get better speeds, but my own experience seems to suggest that the Poplar proxies are not caching *anything* from the USA (ie: virtually nothing goes above 150k) whereas the Colchester/Hersham/Swansea proxies cache *everything* I look at from the USA (ie: virtually all sites at 350-370k), which cannot be right.
I hope it is something as simple as RWIN values on the non Inktomi proxies, maybe that can be fixed fairly easily and bring them(Poplar and other slow ones) into line with the Inktomi Proxies.
In my own (admittedly non scientific) testing - the Proxies I get good speeds from are all Inktomi (according to Robins page - but someone told me that page was out of date).
cheers
