This report used the POSIX socket but not the URING socket implementation in SPDK.
And in the test we use nvme bdev, the uring_bdev (which using the kernel devices) are not
included in the test report.

Subject: [SPDK] Query regarding SPDK NVMe-oF TCP performance.
I’m looking at NVMe-oF TCP performance report for SPDKv20.10 from URL
Would like to know whether it was measured by enabling io_uring support at bdev layer?
As per v19.04 change log, it looks like io_uring was supported from that version
A bdev module that issues I/O to kernel block devices using the new io_uring Linux kernel
API was added. This module requires liburing.
