I don't get the point why continuing by comparing the last byte is better than comparing the second byte.

If you want a real boost you should consider another data-structure, instead of \0 as separator encode the length of the coming snippet. like this you can avoid tests which cross borders and you can take the value as offset to the next snippet.

In other words when checking if a 300 byte snippet is included within a 400 byte one you only need to check 100 possible slides.
