Abstract: Methods and systems for processing input/output (“I/O”) requests in a networked storage environment are disclosed. One method included polling, by a processor, a receive queue at a first polling rate to identify I/O requests received by the receive queue to read data from or write data to a storage device; determining, by the processor that a hit rate has reached a threshold value, the hit rate indicating a number of pending I/O requests at the receive queue, in response to the receive queue being polled at the first polling rate; and modifying, by the processor, the first polling rate to a second polling rate, in response to the hit rate reaching the threshold value.

Abstract: Methods and systems for processing input/output (“I/O”) requests are disclosed. One method includes identifying, a the target, a granular size to split a write request into a plurality of write requests, based on utilization of a processor of the target configured to process input/output (I/O) requests, the granular size indicating a number of the plurality of write requests; generating, by the target, a plurality of read requests to a storage server, each read request corresponding one of the plurality of write requests; issuing, by the target, the plurality of write requests to a storage device controller, in response to receiving data for the plurality of read requests from the storage server; and transmitting, by the target, a completion notification indicating completion of the write request to the storage server, in response to the storage device controller writing data for each of the plurality of write requests.
