Cache Hits Thresholds

Copy Read Hits Percent (Thresholds Supported): Cache Copy Read Hits Percent is the percentage of cache copy read requests that hit the cache, that is, they did not require a disk read in order to provide access to the page in the cache.  A copy read is a file read operation that is satisfied by a memory copy from a page in the cache to the application's buffer.

Note:  The higher the value, the better the performance. Thresholds limits have to be set accordingly.
