并发执行结果

还没测试过 目前用的 RDS ,如果附件能够上阿里云 OSS 也是可以的,主站再cdn 可以扛不少

回复#2 @remenbo :现在这个网站一天这么点PV考虑这些还太遥远了,目前的架构单个VPS支撑一天几百万的访问量是没问题的。

搞这些得等日访问量有那么几十万了再说。

回复#3 @lincanbin :我一个wp博客  日IP只有6k 天天满负荷,现在只有cdn才缓解了

回复#4 @remenbo :WordPress就这鸟样,单页渲染时间很容易就破100ms。

之前我一个 512M的VPS装了WordPress,没几个流量,但是天天内存溢出挤掉mysqld或者httpd。
