Phoronix: Intel Xeon Ice Lake, Gen2 Optane + Linux's IO_uring Yielding Up To 2.58M IOPS Per Core

The Linux IO_uring interface for driving some major efficiency improvements in the Linux I/O stack is really screaming when paired with Intel's next-gen Ice Lake Xeon server platforms and the Intel Gen2 "Alder Stream" Optane solid-state drives...

Reading some of the blog posts about figuring out how to best integrate io_uring with rust's async/.await makes me think that io_uring+rust has a bright future.

I have no idea what a single-core of a present-gen system with something like a fast NVME drive could do compared to these numbers, but I'll give the io_uring guys a lot of credit for making sure that the I/O subsystem isn't holding back the hardware. [Edit: Check out the full Twitter thread and he posts some details of larger I/O blocks and shows the older asynchronous I/O system in comparison... io_uring completely demolishes it in performance and lets the hardware shine.]
