DB Cache Reloaded

更新：DB Cache Reloaded MS不更新了又和wordpress3.1不兼容，可喜的是又有人接下来了那就是DB Cache Reloaded Fix，详情请移步官方插件搜索。

我的博客没有使用有名的WP Super Cache或者WP-Cache，因为我的访问量太少，使用于否意义不大，DB Cache Reloaded到是符合我的心意。我今天进行了专门的试验，使用前后环境都一样：IE清空所有东西，比如缓存、cookie、历史记录等。

数据来看，插件作用相当不错。数据库49.44次查询减少到26次。嗯，页面打开速度来讲，感觉无明显变化。

这个插件使用相当亲民，上传启用就对了。设置方面，Enable打勾就成，Expire a cached query after、Cache filter和Load stats template默认值就对了，不用修改。关于Advanced大家不用去看，只有在网页源代码中出现 0或者-1的cached queries时使用。

没使用插件：
