I have prepared a performance evaluation for you to review here:

You can download the notebook here:

I hope my approach & evaluation is not to naive. Please let me know
whether you think this approach would be a viable alternative to use in
find_peaks. In that case I'd start a new PR to add this functionality
before merging the one we are currently discussing.

Best regards,
Lars
