// CPU的总量（单位：HZ）及CPU的相关信息 
CpuInfo infos[] = sigar.getCpuInfoList(); 
for (int i = 0; i < infos.length; i++) {// 不管是单块CPU还是多CPU都适用 
  CpuInfo info = infos[i]; 
  print("mhz=" + info.getMhz());// CPU的总量MHz 
  print("vendor=" + info.getVendor());// 获得CPU的卖主，如：Intel 
  print("model=" + info.getModel());// 获得CPU的类别，如：Celeron 
  print("cache size=" + info.getCacheSize());// 缓冲存储器数量
