Description

virtiofsd currently does all I/O synchronously, either using a single thread or multi-thread. We're going to experiment with adding an asynchronous I/O (AIO) engine to virtiofsd (io_uring, linux aio etc). This isn't a hard requirement for support, but rather an exploration into its potential to significantly improve performance. The goal is to see if and how much performance can be improved by supporting AIO.

What SSTs and Layered Product teams should review this?
