ARM下KVM虚拟化的损耗验证--redis

ARM下KVM虚拟化的损耗验证

---

摘要

看Windows 上面的 Workstation的虚拟机的 网络层的延迟特别高.
突然想之前统计都是直接在本地验证的, 只考虑了虚拟化CPU的性能损耗
没有考虑虚拟化层网络层的损耗. 

所以想验证完了 Windows 和 intel平台 再抓紧验证一下
ARM平台的宿主机和KVM下面的虚拟机的redis性能比较

---

比较结果

测试命令:
虚拟机, 物理机使用类似的命令
./redis-benchmark -h 10.110.xxx.xxx -p 16379 -a xxxxx  -n 200000 -c 20 -q

测试结果:
出去MSET 虚拟机比物理机性能好之外.
都是物理机比虚拟机性能好很多.
算数平均值是 95.5%
感觉KVM的损耗还是非常低的.
