Abstract
In a compression processing storage system, using a pool of compression cores, the compression cores are assigned to process either compression operations, decompression operations, or decompression and compression operations, which are scheduled for processing. A maximum number of the compression cores are set for processing only the decompression operations, thereby lowering a decompression latency. A minimal number of the compression cores are allocated for processing the compression operations, thereby increasing compression latency. Upon reaching a throughput limit for the compression operations that causes the minimal number of the plurality of compression cores to reach a busy status, the minimal number of the plurality of compression cores for processing the compression operations is increased.
