If your driver can handle the current (it requires doubling the
current when you switch from series to parallel) then parallel
will allow almost 4 x the speed at the same torque, as the
inductance is reduced to 1/4 of the series value.

You may find, if your holding torque is adequate, that going parallel
even with less than 2 x current will give a big boost in torque at
higher speeds. Try it and see!
