I have a VPS and last night I paid to have it upgraded to 2.5GB of RAM. When they told me it was done I notice that I'm only getting 2.2GB of RAM for my server (using /gc in game it says I only have 2GB). I submitted a support ticket stating that I'm missing RAM and they replied: "The memory is all there. We've found that by not allocating the entire amount to the java memory heap allows for better performance because it will use more than just the heap." Is there any truth behind this? Does your XMS = XMX? On average I have about 25 players online and it gets up to the mid 30s. CPU usage is normally 30-40% and RAM usage is normally 60-70%. I need more memory to add additional plugins and for multiple worlds.
