How does Xtreme’s Shared Cache help?

Answer
--------------------------------------------------------------------------------
A cache server collects copies of information that can be immediately available if required again. In the case of Internet access, having information stored locally in a cache means that time is not wasted going out to the Internet to retrieve information a second (third, fourth, etc.) time. Caching itself is not a new concept, in fact most browsers provide caching. Cache servers however bring caching into a shared environment where its usefulness is dramatically increased.

Typically, cached information is stored on a First-In, First-Out (FIFO) basis. This means that as newer information is added to the cache, the oldest information is pushed out if additional space is required. Intelligence is also built in to an Internet cache server so that the date and time of the information stored within the cache can be compared to the date and time of the information available on the Internet. This ensures the freshest copy of the information will always be presented to the user.

With Xtreme Fone.net’s Shared Cache versus no cache, you can expect to see performance increases of up to 300% (as found in independent studies). How about other proxy/caching servers? They also provide a benefit over not using a cache. However, that same independent study found that Xtreme's Shared Cache is the highest performing cache when compared against those found in other proxy servers.
