Hey friend,

I would go for smaller numbers. If you need a single PHP process to load that much memory, I propose that the effort is better spent optimizing the application to use less memory. That said, it never hurts to try anything and see what happens :)


Hello there,

You can apply these values to your WordPress application, but usually, a WordPress website won’t need that much memory to handle a PHP process even when the site is busy. I will recommend you to set the limit lower and in case you run into the issue to troubleshoot what went wrong and the issue was related to process timing out or the server running out of memory and etc.
