Heavy plugins might rely heavily on adding data to `Options Autoload Query Size`. Poorly written plugins causing WP performance degradation have been found to constantly increase this query result size. #### Time Metrics ‘Options Autoload Query Time’ is measured in milliseconds (ms) 0 ms – great performance below one millisecond 1-2 ms – good performance 3-5 ms– OK performance 50+ ms – poor performance should be investigated #### Size Metrics ‘Options Autoload Size’ is measured in Bytes If you have the control to enable the database server wide query cache – configure query_cache_limit to be larger than `Options Autoload Size` 20,000 Bytes – freshly installed clean wordpress site 30,000 Bytes – small wordpress site 50,000 Bytes – medium wordpress site 250,000 Bytes – large wordpress site 2,000,000 + Bytes – too large should be investigated ( `all above are rough metrics` ) ## 屏幕截图 * [[ * Active query cache stats * [[ * Disabled query cache stats * [[ * Execute database command RESET QUERY CACHE ## 常见问题 ### This plugin improves page load performance ? No, This plugin in itself does not improve performance by being installed, this plugin only measures time and size of database query. ### This plugin improves database performance ? No, This plugin in itself does not improve performance by being installed, an administrator should use the dashboard widget to measure, monitor and identify problems. ### Must database query cache be enabled ? No, This plugin measures time and size of a very important database query and these measurements should be valuable to an administrator whether database query cache is enabled or not. ## 评价 此插件暂无评价。 ## 贡献者及开发者 「MySQL query cache stats」是开源软件。 以下人员对此插件做出了贡献。 贡献者 * [ Moris Papasmadov ](https://profiles.wordpress.org/morisdov/) [帮助将「MySQL query cache stats」翻译成简体中文。](https://translate.wordpress.org/projects/wp-plugins/mysql-query-cache-stats) ### 对开发感兴趣吗? 您可以[浏览代码](https://plugins.trac.wordpress.org/browser/mysql-query-cache-stats/)， 查看[SVN仓库](https://plugins.svn.wordpress.org/mysql-query-cache-stats/)，或通过 [RSS](https://plugins.trac.wordpress.org/log/mysql-query-cache-stats/?limit=100&mode=stop_on_copy&format=rss) 订阅[开发日志](https://plugins.trac.wordpress.org/log/mysql-query-cache-stats/)。 ## 更新日志 #### 1.0.4 * Added wp_options Autoload Query Time #### 1.0.3 * Added wp_options Autoload Size #### 1.0.2 * Added Database Size * Added Refresh button #### 1.0.1 * Added Questions, removed Queries Query cache does not cache statements executed within stored programs.
