The delays aren't because they can't load the boats fast enough at Dover, it's because they take forever to unload at Calais. There's only so many boats in the ferry fleet.

And the reason they take forever is because instead of just waltzing through customs waving your EU passport like we did in 2019, now the Frenchies have to stop every British person and check their passport. For one, you're no longer allowed to spend more than 180 days a year in an EU country, so they have to check that and then stamp the date of entry in it. No more getting waved through for you, Sovereignty Boy.
