System.Diagnostics.PerformanceCounter and % Processor Time on multi-core or multi-cpu
1. “Process(…)\% Processor Time” can go up to N*100 (where N is the number of CPUs) because it adds up the CPU usage of the requested process across all the CPUs.
2. “Process(_Total)\% Processor Time” should always be around N*100 (where N is the number CPUs) because it adds up the CPU usage of each process, including the idle process.
3. “Processor(…)\% Processor Time” can go up to 100 because it’s the CPU usage of the requested CPU.
4. “Processor(_Total)\% Processor Time” can go up to 100 because it’s the average CPU usage across all CPUs.
可能是cpu比较多的意思？追问cpu 是2个2核的，最大4K怎么算也不对的
