Ariadne Conill, creator of the Audacious music player, initiator of the IRCv3 protocol development, and leader of the Alpine Linux security team, conducted a study on how to optimize the cat utility, which outputs one or more files to the standard output stream. Two optimization options have been proposed for improving the performance of cat in Linux, based on the use of the system calls sendfile and splice for directly copying data between file descriptors at the kernel level without switching context to user space. <\/p>\n
