Ecommerce store. Built on OceanWP with Elementor/Woocommerce.
I installed image optimization and W3 total cache, disabled minify and got a mobile speed of 64 up from 20.
Now without making a change its back down to 20 mobile speed a couple of months on.
At this point I am considering rebuilding the site fresh page by page on my second domain and then transferring it.
Even the blank contact us page is slow.
