DB Cache Reloaded源于DB Cache插件，在DB Cache原作者停止更新后，另一位wordpress的爱好者继承并开发了DB Cache Reloaded。原理是通过建立数据库缓存，来减少数据库查询次数，从而达到加速blog访问速度的目的。

DB Cache Reloaded的安装与设置非常简单，只需解压并上传至wp-content/plugins/目录下，后台启用，并在设置页中选中ENABLE，在设置数据库缓存的更新时间就可以了。

如果一切顺利，你会在/wp-content/目录下，看见tmp高速缓存文件目录。在页面源码中也可以查阅到DB Cache Reloaded的工作状态，比如类似这样的代码：

<!-- footer END -->

<!-- Generated in 0.379 seconds. Made 7 queries to database and 62 cached queries. Memory used - 23.2MB -->
<!-- Cached by DB Cache Reloaded –>

DB Cache Reloaded之前发布的1.1版本，会与一些wordpress的分页导航插件，比如很多人使用的wp-PageNavi产生冲突，致使分页功能无法显示，好在作者已经及时的解决了bug，并更新到DB Cache Reloaded 1.2版本。

1.2

• Fix: queries were not cached starting from first not cached query;
• Fix: all queries were cached in the same directory instead of dedicated subdirectories;
• Fix: total row count calculation did not work for complex queries (usually observed as no pagination problem);
• Added support for DBCR_SAVEQUERIES define to enable extended query logging (as compared to default SAVEQUERIES support)

1.1

• Added Polish translation;
• Added Italian translation (thanks Iacopo);
• Show error in admin section when wpdb class already exists (this should not happen, but I got few reports about this);
• Fix: do not cause fatal error when plugin is deleted manually without deactivating it first (in this case wp-content/db.php is left). Instead display error in admin section;
• Added support for custom plugin directory;
• Some performance improvements;
• Show message in admin section when plugin is activated but caching is not enabled

1.0.1

• Fix: statistics are not working

1.0

• Took DB Cache 0.6 as a baseline;
• Merged changes done in WordPress 2.9 for the wpdb class (this fixes annoying tags bug);
• Cleaned up code, moved almost everything from global scope to class;
• Secured settings page with nonces;
• Switched to po/mo files for internationalisation
