Why Does Killer Network Service Cause High CPU Usage?

One of the most common complaints amongst users regarding Killer Network Service is that it causes high CPU usage. This is because, Killer Network Service handles too many processes simultaneously. It also modifies other processes to boost the gaming performance for you. 

Many times, all these processes may not be compatible with each other or with the system.
