The PHP Memory limit setting in the control panel controls how much memory in RAM one PHP process is allowed to use on the site in question. This setting should be as low as possible for the application running. One PHP process is usually a page view.
Memory limit is not the same as RAM
While RAM is the total available memory, the memory limit is per PHP process. That means that your site can consume e.g 10 GB of RAM, with a memory limit of 256 MB. We do not limit the amount of RAM you can use, just the memory limit.
Recommended PHP memory settings
- A healthy standard WordPress site shouldn’t need more than 128MB
- A healthy standard WooCommerce site shouldn’t need more than 256MB
- A healthy standard Magento site shouldn’t need more than 768MB
This might be different in your application.
