Caching dramatically improves page load time, transforming your user experience. ISPs can improve user experience to gain an edge over the competition and reduce subscriber churn.
When one of your users downloads an object, a copy is stored on the cache. Subsequent requests for the same file can then be served instantly, without re-downloading. As well as using less bandwidth, this improves response times for your users.
In most cases, a transformed user experience is at least a strong #2 reason for deploying a cache. In many cases, it is actually the #1 driver, particularly:
- in higher/cheaper bandwidth locations
- for Wireless ISPs that rely on Satellite connections – caching delivers an even greater improvement in internet access speeds due to the significant reduction in latency for cached content.
