WitrynaFor such optimization, information about the access locality is needed in order to help the user in the tasks of data allocation, data transformation, and code transformation which are often used to enhance the utilization of cached data towards a better cache hit rate. WitrynaFor read operations, the SSD Cache “hit rate” represents the ratio of cache hits, whereby data requests can be fulfilled by the SSD Cache. A higher hit rate indicates fewer read operations on disks and therefore lower I/O latency. Conversely, a lower hit rate indicates that most data being read is fetched from disks, where response dickey\\u0027s pit bbq
