Is there any plan to do so in the future? Just to see whether that provides better performance than POSIX socket. Regards, Senthil Kumar V.

Hi Senthil, 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.

Hi, I’m looking at NVMe-oF TCP performance report for SPDKv20.10 from URL https://ci.spdk.io/download/performance-reports/SPDK_tcp_perf_report_2010.... 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 onwards. io_uring 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.
