Abstract
In a compression processing storage system, using a pool of encryption processing cores, the encryption processing cores are assigned to process either encryption operations, decryption operations, and decryption and encryption operations, that are scheduled for processing. A maximum number of the encryption processing cores are set for processing only the decryption operations, thereby lowering a decryption latency. A minimal number of the encryption processing cores are allocated for processing the encryption operations, thereby increasing encryption latency. The encryption operations, the decryption operations, and the decryption and encryption operations are scheduled between the pool of the plurality of processing cores according to a thread weight value (TWV) that is assigned to each one of the plurality of processing cores having a difference in processing power.
