最近与几个大佬闲聊之际，发现很多人都在不约而同地吐槽 Azure 的效能。综合的来的意见不外乎是云盘 I/O 过慢（HDD/SDD 一样卡）、主机响应迟钝没反应、运行更新耗时大半天，期间 CPU 效能满载或时处于半宕机状态等等糟心体验，还贵。贵，是毋庸置疑的，毕竟产品品牌定位就是高端货，不可能做到灵车的价格。但我想说的是很多时候产品本身并无问题，只是食用姿势不对。

After all, my Hyper-V server comes with an abundance of CPU power and memory, and I can always assign more vCPU/RAM or create additional VM at little to no cost.
