If you don’t have gauges in your line, wrap the lines with electric tape and use an infrared gun to get supply and return temps then set your pump speeds to try to get a 20 degree differential when each loop is under a load.

I am guessing that you mean the recover time of the OWB. If that is what you meant, the reason for the faster recovery time is most likely to poor mixing in the water jacket and you are only heating the water at the top. Have you noticed if the stove cycles more often on low?

My pump which came from Ridgewood currently is set at 2 out of 3.  When the temp gets really cold a faster pump speed will deliver more heat.  I also bump up my high temp to 190 with a differential of 10.
