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. You need a minimum of 4 PHP workers to run an eCommerce website, which would cost you $100 per month on your own. If you’re on my Kinsta WordPress Hosting plan, you will automatically get enterprise-level PHP workers (12 workers), which would cost you at least $1,200 per month on your own.
