A pull request for the Microsoft .NET Runtime build on Linux to use IO_uring for sockets is showing some massive performance benefits.

Ben Adams of Illyriad Games and a .NET contributor opened the pull request to use IO_uring for sockets on Linux. This implementation is a complete, "production grade" IO_uring socket I/O engine for .NET's System.Net.Sockets layer. With the proposed code it's currently opt-in via the OTNET_SYSTEM_NET_SOCKETS_IO_URING=1 environment variable.
