Duplicate shop pages,4 seconds to load each page

hi i am new here and have started using cloudflare for over a week, i am getting duplicate shop pages on my wordpress site when i use gtmetrix,each page takes over 4 seconds to load.
i have only one shop page.
i am using wp fastest cache,also real simple ssl. and woocommerce.
any help would be great
thanks

That’s just WordPress rewriting the URL to add a slash at the end. But even that’s super slow, and there’s no good reason for that. WooCommerce needs good hosting for decent performance. Cloudflare can’t speed up page loads for WooCommerce shoppers.

i did a server speed test,i come back as excellent.i have another site with the same hosting and have no problems,i dont have cloud fair on it. and no duplicate shop page.
