Abstract
Methods and systems for improving caching accuracy utilizing snapshot technology are provided. One or more requests for data are received. When the requests for data return valid data, the valid data is stored within a cache. The response performance of a server device is monitored. When the response performance of the server device is above a predetermined threshold, one or more snapshot versions of a memory block are taken. The memory block may include the current state of the valid data at the time the snapshot version was taken. Upon receiving a warm-up cache signal for the cache, a snapshot version is used to populate the cache and sent to a client device.
