1、编译器优化，for循环实际根本没执行，直接跳过去了，所以时间为0。2、clock计算的是程序占用cpu的时间，如果你的程序执行的动作很少，那么clock算出的时间也很少。3、建议使用time gettimeofday函数来计时。

监测CPU温度用vcgencmdmeasure_temp,持续高温时加装散热片。被动散热设备建议限制CPU频率,在/config.txt设置arm_freq=800降低功耗。机箱内部使用导热硅胶垫改善热传导,安装低速风扇并配置温控调速策略。 远程访问配置 在路由器设置DDNS动态域名解析,开放9000端口转发TCP流量。启用SSL加密连接,用Let’sEncrypt申请免费证书。
