This read-only integer reports the percentage of cache copy-read requests that were satisfied entirely from the cache without requiring a disk read, where a copy read is a file read serviced via a memory copy to the application buffer, a method used by the LAN Redirector and LAN Server. An admin watches this as an efficiency measure of the file-system cache for small-transfer read workloads. For example, a falling cpqOsCacheCopyReadHitsPercent would indicate the cache is increasingly missing and having to fall back to disk reads.
