Common settings are if you are on a dial-up modem a good range would be from 1-5 ports depending on how good your connection is. If you are on a cable or DSL you can run the program between 5 -25 ports. If you notice a number of time-outs try slowing down your ports until you have very few time outs or even none. If that will not work increase your time-outs until you see the submissions going through.
