I'll try WP Rocket
Many friends said it was effective
Mobile loading is fine for me. It depends on many factors. Every site is different.I do have WPRocket, and the loading times on desktop where okay, however, the loading times on Mobile are terrible.
Please adjust your settings to mobile in GTMetrix as most of your customers will be using their mobile phones to visit your site.
