I currently use qemu_aio_set_fd_handler() to implement async output to the backup stream. While that works, performance is much better (during backup) if I use a separate thread to write the data. Is that known behavior, or should aio give about the same performance as using a thread? Or would I get better performance if I use Linux native AIO support?
