I have a Wordpress site, which runs a lot of plug-ins (about 40), resulting in the slow speed of the entire website. It takes about 10 seconds to load a page in many cases. Why should I install so many plug-ins? In fact, it is also to meet more or less different functions, such as SEO, online business system, e-commerce system, SMTP,Cache, Backup, performance tuning, WeChat applet, WeChat login, payment system, statistics system, marketing system, translation system, etc
