History and performance recommendation: is my memory right?

The history charts show players, memory and CPU for the last 24 hours or 7 days. If your RAM is at its limit – or far too large – we tell you honestly.

History on the server page

On your server's overview, the History card shows three charts – switchable between 24 h and 7 days:

  • Players – with the peak in the period (for games that report player counts)
  • Memory – with the peak compared to your limit
  • CPU – 100 % equals one fully used core

We record the values every 5 minutes, so after a new order the first lines appear shortly. Below the charts you'll see what percentage of the time the server was online.

The recommendation

From the memory usage of the last 7 days (only while the server was running) we derive an honest recommendation. It appears at the top of the server page:

  • “Your server is at its limit.” Memory is regularly above 90 % – this often explains lag and crashes. Upgrade to … books the next tier.
  • “You can save money.” Over several days your server didn't even need half of its memory. Switch to … moves you down to a smaller, cheaper tier.

Both buttons open the Change resources page with the suggested tier preselected – you decide there. Don't show again hides the notice for 30 days.

Good to know

  • There is no “at its limit” recommendation for Minecraft (Java): Java always occupies almost all of the assigned memory, even if it doesn't need it.
  • High CPU while plenty of memory is free? Then a higher CPU tier helps more than more RAM.
  • The recommendation also appears in the monthly report.
