what do you expect?

open htop and look at the CPU usage of a single NVT process
what you are doing is 10*4 = 40 NVTs at the same time

use the one above and think about how this should be faster
if you overload them - limit it to one host at the same time
and i bet it will be finally even faster than now because no
overload
