使用阿里云RDS之后一个让人欲哭无泪的下午

非常抱歉！给大家带来可麻烦了！我们都已经欲哭无泪。。。

今天下午是使用阿里云RDS之后访问量最高的一个下午，结果出问题了——大量数据库查询超时。

阿里云DBA一个下午帮着我们优化数据库，但问题没有解决。

我们猜测问题的原因不在数据库本身，因为同样的数据库之前在性能很差的云服务器上也没出现过这个问题。可能是云服务器与RDS之间的网络问题，比如防火墙对网络流量与网络连接数的限制。在出问题期间，我们重启负载均衡中的一台云服务器之后，会有一会儿时间恢复正常（网络连接/流量减少），但很快又出问题。

下图是RDS控制台的流量统计图：

优化一些数据库查询，还有mencache，不过看你的，感觉是阿里云的问题，因为一般这样的流量应该只是导致部分页面打开慢

我给楼主说个题外话，你们博客的案日期归档功能有问题。
http://www.cnblogs.com/cmt/archive/2008/06.html
http://www.cnblogs.com/cmt/archive/2009/02.html
出来的内容都是一样的，根本没有归档。

不知道淘宝网有没有用阿里云呢，向他们取经就能解决问题了！
