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` ) ## Скриншоты * [[ * Active query cache stats * [[ * Disabled query cache stats * [[ * Execute database command RESET QUERY CACHE ## Часто задаваемые вопросы ### 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. ## Отзывы Нет отзывов об этом плагине. ## Участники и разработчики «MySQL query cache stats» — проект с открытым исходным кодом.

Queries differs from Questions in that it also counts statements executed within stored programs.
