Mysql 如何分析WordPress安装的慢速查询日志？

我在WordPress安装中遇到一些性能问题。我已经运行了多个慢速查询测试，虽然我确实看到它们之间存在一些一致性，但我仍然无法找出问题所在。以下是我多次看到的一些查询：

SET timestamp=1333980631;
SELECT SQL_CALC_FOUND_ROWS wp_posts.* FROM wp_posts INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) WHERE 1=1 AND ( wp_term_relationships.term_taxonomy_id IN (1442,4054) ) AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private') GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 2;

我注意到，

wp\u术语分类法

似乎与

wp\u帖子

以及其他一些文章一起出现了。我的问题是，如何缩小这些结果的范围并找出问题所在？

您可以：

用于对problematics插件进行基准测试和精确定位

用于查找问题

用于转储用于查询等的数据

显示的查询类似于通常的wp admin查询，或用于定义在列表中显示多少页面的寻呼机查询

您也可以尝试最简单的方法—逐个禁用插件，以确定哪个插件生成了有问题的查询。

谢谢！我今天将对此进行调查。
