That's because you didn't batched your pipes. The message will pass the
router for each recipient, but you can run a pipe for each batch of X
recipients where X defaults to 1. If X is set to 100 (of course, if this
many recipients can be handle by your command at the same time), all
messages should be scanned only once if 100 is your maximum number of
recipients accepted by Exim.
