503 error and very slow add to cart response

when adding products to the cart it takes a very long to actually take place. please check why. my developer said it might need more RAM?

If your developer is suggesting more RAM for you web server I presume, and you’re not using cloudflare for the actual hosting of the site, then its likely that you should follow their advice.

This may not have anything to do with Cloudflare if you’re only using them for DNS.
