Love it.

I'm trying to understand why all command line tools don't use io_uring.

As an example, all my nvme's on usb 3.2 gen 2 only reach 740MB/s peak.

If I use tools with aio or io_uring I get 1005MB/s.

I know I may not be copying many files simultaneously every time, but the queue length strategies and the fewer locks also help I guess.

io_uring is a security nightmare.
