Why does not the function in subject use mmap? In my tests, using mmap instead of reading the file block at a time gave 17-26% performance improvement: The new method: 135735 microseconds per iteration The old method: 164525 microseconds per iteration The new method: 387283 microseconds per iteration The old method: 529743 microseconds per iteration Should I submit patches, or is there a good reason?
