这三家我都有使用
先说 使用感受
这几天有想法 测一下 这三家提供的 mysql 读写性能如何, 于是写了下面的脚本。
先说一下这三家 mysql 的配置:
所以这是一个不严谨的测试,因为这些机器都是早就买好的。所以无法做到测试环境一模一样。
每家各测试多次,结果比较稳定,就选取其中的一次结果:
INSERT ONE 3.25666999817
INSERT MANY 0.217604875565
QUERY 3.51868581772
INSERT ONE 5.17626905441
INSERT MANY 1.33850288391
QUERY 2.40842795372
INSERT ONE 5.36786603928
INSERT MANY 0.239859104156
QUERY 5.58612704277

只有真正的用户才会认证的做这样的性能测试, 不像很多人在没有深度使用之前,就在网络上主观的乱喷
