背景
最近想验证一下不同主频下 CPU性能相关内容.
本来想开启一个高主频的 虚拟机
但是经过自己一翻 百度 bing
发现大部分资料告知我
虚拟机没法调整主频.
WTF 只能用物理机来进行相关的处理.
经过十分钟的努力
得出结论
Redis的性能在相同架构, 相同型号的CPU上面
与主频的大小成等比率关系.
物理机的基本信息获取
服务器配置:
鲲鹏920 2.6G 1T内存
具体信息:
frequency-info --policy
analyzing CPU 0:
current policy: frequency should be within 1000 MHz and 2.60 GHz.
The governor "performance" may decide which speed to use
within this range.
cpupower -c all frequency-info
analyzing CPU 127:
driver: cppc_cpufreq
CPUs which run at the same hardware frequency: 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127
CPUs which need to have their frequency coordinated by software: 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127
maximum transition latency: Cannot determine or is not supported.
hardware limits: 200 MHz - 2.60 GHz
available cpufreq governors: conservative ondemand userspace powersave performance
current policy: frequency should be within 1000 MHz and 2.60 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: 2.60 GHz (asserted by call to hardware)
设置CPU频率的方式
cpupower -c all frequency-set -f 2.5Ghz
cpupower -c all frequency-set -f 2.0Ghz
cpupower -c all frequency-set -f 1.0Ghz
