how many times a hour should the water go through the sump?

It does? how does that work, it is a filter, why so much flow the water falls out of the overflow box at a constant unless you are running a siphon ?

Of course you will, if you slow it down by half the surfactants delivered to the skimmer will be double in the same time frame
