Pizza is actually cooked hot and fast compared to most other dishes already. I want the back of the oven to be 500C / 930F before I start. This is why a pizza oven is specialised equipment, a standard-issue kitchen oven doesn't get that hot (usually tops out under 300C), so doesn't give nearly as good results.
And why it takes about 90-120 seconds per pizza to cook in a proper pizza oven.
Though IDK, maybe Dominos process is different to this, for their different pizza style.
If you wanted to cook even faster, then less toppings would help, but you may not want that, though you might get a good result in 60 seconds.
And an even hotter might not work- I suspect that it would not give as good results, e.g. burned in one area and undercooked in another.
