Caches are designed to reduce the latency of internet requests as a whole.
A cache 'hit' (where it satisfies the request from local disk) should take tens of milliseconds (ms). A 'miss' (where it has to fetch the object from the remote web server via the internet) takes several hundreds to thousands of ms.
A slightly older doc on the problems of latency (but the principles still hold true today) is:

Thank you for that link I will read it later tonight when I have peace. I must say that the proxies was working ok recently but last night they blew it big time. As soon as it was too late to call in the proxies for me died completely. Unable to access any website.. MSN, Yahoo, ICQ and AIM alsom MIRC chatroom all still worked but anything that needed the http was dead.... this lasted about 30 mins...
Need some sort of way to communicate these problems when faults is closed or 24 hour cover..
