In the current version of FASTER C++, on Linux, we use libaio for async IO handling. It is a known issue that libaio is not very efficient. Recently, io_uring is released with Linux kernel 5.1, which advertises to be a high performance aysnc IO library. It would be useful to try it and see if we can improve disk performance on Linux by replacing libaio with it.

More details for io_uring can be found here: http://kernel.dk/io_uring.pdf
