If I have it wrong then I am willing to learn so come on techies teach me the ideas behind proxies and what benefit they give customers!

Not sure exactly what the above is saying, but if your question is about the
latency that proxies add to internet requests, then (assuming that the proxy is working correctly, running within specification and there are no network problems) it is negligible compared to the response time via the internet and remote web server. 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:
