proxy problems?

Hi All,

I got the proxy set-up between our site here and in Newbury but at 4:30 last night I got a call saying we were using a high level of bandwidth, the network team investigated and found hobbit to be using 50% of our 2mb connection, is this normal? How can I run tests etc. to see how the proxy is working and are there any settings I might alter to make it use less bandwidth?

Thanks,

Jason.
