Woocommerce- Fix website site speed, potentially change cache?

详细信息

I need someone to fix my website speed, its currently running slow when I use GTMETRIX1. I would like results that show it runs faster on GTMETRIX or some other site where I can see it is faster. 2. I would like it to be faster on MOBILE AND ONLINE3. last time someone made my website faster but this did not last a very long time even though I have not changed my website much so I need someone to make lasting results4. I use WP rocket but it is no longer free, I dont know if I should change it5. PLEASE make sure it does not ruin my cart, some cache plugins have made wierd changes to the cart and add random items to cart for customers or don't let t hem order
