io_poll and sqpoll cause IOPS degradation

[aidosww]

The configuration of io_poll and sqpoll results in file write performance degradation. The environment used is as follows:​ 1、Linux kernel 5.10​ and kernel 6.2 2. The storage device is an SSD.​ 3. With sqpoll and io_poll enabled:​ ======IOPS (WRITE): 47147.57 in 2.12 seconds for 409468928 bytes​ When using the default configuration without enabling the feature:​ ======IOPS (WRITE): 179856.12 in 0.56 seconds for 409468928 bytes

Can anyone help me? Thank you very much.
