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.
