Reducing read latency using a pool of processing cores

摘要

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.

1. A method for reducing read latency in a read processing storage system using a pool of a plurality of CPU cores, comprising:
assigning to each one of the plurality of CPU cores for processing only one of write operations, read operations, and read and write operations that are scheduled for processing; setting a maximum number of the plurality of CPU cores for processing only the read operations, thereby lowering the read latency; and allocating a minimal number of the plurality of CPU cores for processing the write operations, thereby increasing a write latency, wherein 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.
