# Why is caching important in application performance?

Why is [caching](https://www.mindstick.com/blog/43/caching-in-asp-dot-net) important in [application performance](https://www.mindstick.com/forum/159995/what-is-the-role-of-the-node-js-cluster-module-and-how-can-it-improve-application-performance)?

The key factor which improves [application](https://www.mindstick.com/articles/12824/calculator-application-in-android) performance comes from caching technology because it lowers the duration and system resource requirements to access data. The data access performance improves because caching preserves regularly used data in a memory-based location that provides stronger speed and better accessibility. Application performance increases together with user experience improvement through this method.

The application system examines the cache before supplying data upon client requests. The application provides data instantly whenever it can retrieve requests from the cache (a cache hit). The application moves to the original data source only when no cached data exists for the request but retrieves and stores the information for later use. The system prevents repetitive processing activities which in turn lowers demands on both database and external service resources.

The technology of caching proves very helpful when your application handles multiple requests for identical data from the same user population such as product displays or user information or system configuration options. The performance of applications improves through caching because it eliminates redundant computations and queries resulting in increased scalability when the system handles high loads.

Playing a vital role in cost reduction the implementation of caching decreases the need for database access in specific cloud operations that bill customers based on resource usage. Under such circumstances the cache functions as a temporary backup which provides data accessibility when the primary data source becomes unavailable.
