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