Some WordPress websites require more resources when it comes to PHP and this is due to a number of factors. WordPress websites that are highly dynamic. WordPress websites running e-commerce solutions like WooCommerce.  WordPress websites running pages builders like Elementor. Unless you spend a minimum of $600 for a Kinsta Enterprise plan of your own, you will be limited to a max PHP memory allocation of 256M. If you’re on my Kinsta WordPress Hosting plan, you will be able to request enterprise-level PHP allocations, using Kinsta’s support chat.
