We do not mention RAM in our pricing, and there is a good reason for it. It simply doesn’t matter, since we make sure there’s enough. Our servers are configured with a minimum of 64 GB of RAM, usually 128 GB RAM depending on the rest of the server configuration.
memory_limit is what matters
Our plans come with different PHP memory Limits. That means the amount of memory one single PHP process is allowed to use. You can read more about what the PHP memory Limit is here.
