The shorter pathnames is a small improvement only when post processing the output.
Then, you can bundle the names (shortens the command, not so much the run time).
But a + instead of the \; will have an impact. Then find runs cksum with many collected arguments - fewer runs are needed.
Further, compare the speeds of the /usr/bin/find and the freeware find.
