我为一个 Drupal 站点打开了慢速查询，以下是前 10 个慢速查询。关于如何找到它们的来源或起源的任何想法

如果您推荐一些可以回溯查询到所用 View 或模块的工具，那将很有帮助；如果存在这样的事情。如果查看查询引起了共鸣，请帮忙写评论。

非常感谢..

最佳答案

我不会太担心只出现一次的那些。大多数只是 SELECT * FROM big_table 这很可能是通过某些管理员完成的。我不确定什么会获取整个 session 表，这不是很有用。

无论如何，出现不止一次的其他查询很可能是由 View 生成的:

LEFT JOIN term_node term_node_value_0
  ON node.vid = term_node_value_0.vid AND term_node_value_0.tid = N

执行 20 个这样的连接会减慢任何查询，这也是它看起来像 View 的原因。 View 在不知道你真正想做什么的情况下进行通用查询。所以它可以做出任何假设，这就是为什么它在某些情况下可以做出这样疯狂的查询。唯一的解决方法是对 View 进行自定义编码或仅对查询进行自定义编码。当事情有点复杂时， View 很难对术语进行良好的查询，因为术语具有一对多的关系(1 个术语可以关联以构成节点)。

因此，请检查您拥有哪些 View ，您也许可以使用 View UI 中的缓存来处理此问题。

关于Drupal慢查询日志分析，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3854056/
