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.pdf.

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.

Regards,
Senthil Kumar V.
