+1 rough lumber on jointer is perplexing at times. :-)

The challenge is the jointer is only cutting a small portion of the cutoff amount from the highest spots; which makes it look like it’s doing nothing for 1st 4-6 passes. You can get same effect jointing with hand plane.

As others mentioned, if you take off the highest spots with another tool first; jointer is more productive.

Finding the high spots, it helps to get personal with the board, IMHO.
Try dragging a card scraper across the surface, and watch for light underneath. You will see spots that need more scraping/planning/sanding for removal. Mark these spots with colored chalk or crayon. Then either remove the highest spots separately, or watch those areas as jointer does the work. You won’t feel as useless as you watch the marked areas slowly disappear after half dozen passes.

Best Luck.
