2 work prints an hour? Assume that it takes 5 mints to find a negative, put the negative in the enlarger, focus, stop the lens down, if the exposure is not known run a test strip. 1 mint in the developer, 10 seconds in the stop, 1 mint in fixer, followed by 5 mint wash. While test strip 1 is the wash find and print develop another test strip, pull negative 1 from the wash blow dry the test strip, return negative 1 to the enlarger and print work print, then print work print for negative 2 then repeat. Very possible to print 2 prints in 10 mints, I don't see why you cannot print 10 to 12 prints in an hour? I can print more than 10 to 12, I as usually don't need to print test strips for every negative from the same roll.
If you have cold darkroom and cold water and time in the developer is extended then I can see how your production will be slowed.
