Abstract
An apparatus, program product and method utilize a cache payback parameter for selectively and dynamically disabling caching for potentially cacheable operations performed in connection with a memory. The cache payback parameter is tracked concurrently with the performance of a plurality of cacheable operations on a memory, and is used to determine the effectiveness, or potential payback, of caching in a particular implementation or environment. The selective disabling of caching, in turn, is applied at least to future cacheable operations based upon a determination that the cache payback parameter meets a caching disable threshold.
