Method and apparatus for adjusting throughput of storage device

An electronic device, comprising:

• at least one processor;
• at least one memory coupled to the at least one processor and storing instructions to be executed by the at least one processor, the instructions, when executed by the at least one processor, causing the device to perform acts including:
• setting input/output (I/O) delay time of a storage device to be threshold delay time, the threshold delay time being below initial I/O delay time of the storage device;
• obtaining measured throughput of the storage device, the measured throughput being associated with the threshold delay time;
• and
• updating the I/O delay time based on a difference between the measured throughput and target throughput of the storage device to update the measured throughput.

A computer program product for adjusting throughput of a storage device, comprising:

• a non-transitory computer readable medium encoded with computer-executable code, the code configured to enable the execution of:
• setting input/output (I/O) delay time of the storage device to be threshold delay time, the threshold delay time being below initial I/O delay time of the storage device;
• obtaining measured throughput of the storage device, the measured throughput being associated with the threshold delay time;
• and
• updating the I/O delay time based on a difference between the measured throughput and a target throughput of the storage device to update the measured throughput.
