Number of syscalls without the patch -> with the patch: - read the README file, text mode: 17 -> 12 syscalls (-5) - read the README file, binary mode: 15 -> 11 syscalls (-4) - read a binary file of 10 MB: 17 -> 12 syscalls (-5) Quick benchmark open('README').read(); open('README', 'rb').read() in a loop: 359.1 ms -> 335.4 ms (-7%). So it's not really faster.
