I don't think so. It could be auto-disabled for large buffers and the check would only take place when the size of the buffer is the same as the size of the original file. Then, the hash would be calculated on a idle timer that is fired after a command that changes the contents... It is doable, moreover if the current hash function is so inefficient as you say. MD5 is rated at more than a hundred MB/s on not-so-new hardware.
