The Allies controlled fewer big ports close to the front than I do in my game. They did not control either Amsterdam or Rotterdam. They also had the equivalent of at least 20 air units in France. THEY DID NOT HAVE ANY SUPPLY PROBLEMS WHATSOEVER! In fact they had an overabundance of supply.
Well in that case, if the historical ports are indeed not enough for historical deployment (but as I said, I'll leave that debate to players knowing more than me about supply in WWII), I agree that the ports size or effectiveness should be improved to better reflect historical capacities.
Probably better, if needed, to play with port size than port effectiveness (not to change the supply level in other places such as in Africa for example).
Perhaps the biggest problem is that the game doesn't have enough diversity in port size. For example, the port of Tripoli in Libya (a size 6 port) could in WWII handle only about 46,000 tons per month. But this is what I found on Wikipedia about the port of Antwerp:
"The capture of Antwerp would have solved all supply problems. The port could handle 1,000 ships at a time weighing up to 19,000 tons each. Antwerp had 10 square miles of docks, 20 miles of water front, and 600 cranes. Senior Allied commanders counted on Antwerp handing 40,000 tons of supplies a day – when it was captured."
So Antwerp could handle in one day almost the same amount of cargo that Tripoli could handle in an entire month. So the difference in port size between them should be about 25X, not just the 1.5X that it is. And don't get me started on the difference between Antwerp and Tobruk. This is why, after capturing Antwerp (and clearing the Walchern Islands) the Allies made no attempt to capture Rotterdam or Amsterdam. Even in the Spring of 45 no serious attempt was made to capture them because the Allies didn't need them. So make Antwerp a size 125 Port (and increase the size of other ports like Marseilles, Cherbourg, etc) and the problem goes away. Perhaps couple this with ports repairing over time once captured.
