WordPress的千类崩溃网站

Question

我有一个大型网站，目前每天大约有1万个唯一身份访问者，我有2000个类别，12k个标签，36k个自定义分类法。

这不是设计缺陷，因为我使用它作为观看在线电影的网站，还列出了Seasons类别以及类似内容，自定义分类法是Actor，regizor等。

问题是我的主机一直在使用100％处理器崩溃，资源不会成为问题，因为我有自己的服务器，带有4xXeon，64 GB内存。

我已经隔离了问题，例如由于查询速度非常慢，我有什么选择？ ：

(hundreds of numbers) ...,49740,49779) 

这是表的转储

Answer 1

“行检查” = 420K-缺少索引。

可能丢失：

INDEX(term_taxonomy_id, object_id)

请提供两个表的SHOW CREATE TABLE 。

innodb_buffer_pool_size的值是innodb_buffer_pool_size ？
