AppPlatform "Assuming 512MB of RAM" even on Pro instance

I’m running an nginx-php stack on AppPlatform (for WordPress). The runtime log always says “Assuming 512MB of RAM” even though I’m using Pro instance with 1GB RAM. Is there anyway to force that number?

Hey there!

The amount of RAM provided to PHP by default is dependent on the RAM specified in the plan and will not use the full amount available by default. To change that you can set a .user.ini file in the same location as the php files you are serving. In that file you can specify the php_memory_limit to a value that you need. We’d recommend not using the full amount provided in the plan size to be sure your other processes have sufficient resources.
