Or strace yes. It seems that rsync does an lstat for any file before
applying the exclude rules.
Possible optimisation?

Since the backup with --exclude="tmp/" is fast it may be acceptable to
make two passes, one for the main stuff, the second to populate the
tmp/ directories.
Example:
rsync -a --delete --exclude='tmp/' --filter='protect tmp/' /home/ /backup/home
(cd /home && find . -name tmp -prune -print ) \
| rsync -a --files-from - /home/ /backup/home
