红帽全球峰会A.4. tuned
TuneD 是一个调优守护进程，可通过设置调优配置文件来调整操作系统，以便在特定工作负载下更好地执行。它还可以配置为响应 CPU 和网络使用的变化，并调整设置以提高活动设备的性能并降低不活动设备的功耗。
要配置动态性能优化行为，请编辑
/etc/tuned/tuned-main.conf 文件中的 dynamic_tuning 参数。然后 tuned 会定期分析系统统计信息，并使用它们更新您的系统调优设置。您可以使用 update_interval 参数在这些更新之间配置时间间隔（以秒为单位）。
有关 tuned 的详情，请查看 man page：
man tuned
$ man tuned
