Thank you for your quick response. If you can visit so fast, it is already more convincing than the speed measuring website. If you can close the post after replying, because I can’t find the button setting to finish the work order of the post..
First: I have disabled the Slider Revolution plugin according to your suggestion, because I don’t know what effect this plugin has on the theme, so I dare not delete it.
Second: Can WP Rocket plugin be replaced with Autoptimize plugin? Because of its price and other optimizations that may conflict with the cache I ‘ve already done, I don’t want to use WP Rocket plugin.
