PerformanceCounter cpuload = new PerformanceCounter();
cpuload.CategoryName = "Processor";
cpuload.CounterName = "% Processor Time";
cpuload.InstanceName = "_Total";
Console.WriteLine(cpuload.NextValue() + "%");

The output is always 0%, while the cpuload.RawValue is like 736861484375 or so, what happened at NextValue()?
