Your rayhl.org minecraft server may be hosted on one of two nodes, each with their own set of specifications.
You can check which node you are using by going to the panel » server » settings tab » Debug Information.
The 'Node' will either be 'm4-node', or 'main-node'.
Which node you are on will only really affect your CPU's performence, since you do not get the node's full RAM or storage for a server.
The Maximum Specifications for each node are the maximum that can be allocated to any one or multiple servers.
You can see your amount of RAM and Storage in the panel » server » Console Tab and looking at "Disk" and "Memory" on the side cards.
