添加配置文件

Processor线程编号.use = "TRUE/FALSE"

如你是13700K 那么你的线程就是0-15是大核心 16-23是小核心

如指定大核心那么需要添加的配置文件如下

Processor0.use = "TRUE"
Processor1.use = "TRUE"
Processor2.use = "TRUE"
Processor3.use = "TRUE"
Processor4.use = "TRUE"
Processor5.use = "TRUE"
Processor6.use = "TRUE"
Processor7.use = "TRUE"
Processor8.use = "TRUE"
Processor9.use = "TRUE"
Processor10.use = "TRUE"
Processor11.use = "TRUE"
Processor12.use = "TRUE"
Processor13.use = "TRUE"
Processor14.use = "TRUE"
Processor15.use = "TRUE"
Processor16.use = "FALSE"
Processor17.use = "FALSE"
Processor18.use = "FALSE"
Processor19.use = "FALSE"
Processor20.use = "FALSE"
Processor21.use = "FALSE"
Processor22.use = "FALSE"
Processor23.use = "FALSE"
