[SPDK] Re: Query regarding SPDK NVMe-oF TCP performance.

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.
