Having less than 90% CPU usage

Problem Description

Issue

The issue I am having is that the server has been crashing on a regular basis when overloaded with very few things happening in the server. When there’s 3-4 people online the server is heavily overloaded although the memory capacity doesn’t exceed 2000mb out of 3600. The CPU is at a consistent 90%+ usage when multiple people are in and even when only one person is online and is traveling quickly. I feel like one person using an “elytra” shouldn’t overwhelm an entire server with those powerful AMD processors you advertise. The server is running 2 very basic plugins and one voice chat mod, which I also don’t see increasing the stress all too much. Except for the voice chat and some few quality of life plugins it is a completely vanilla server.

The simulation- and render distance is also only set at 15.

If you could either tell me a fix or a believable explanation to this problem that would be appreciated!

Thanks in advance.

Reproduction Steps

  • Setup the server with spigot
  • Downloaded 2 plugins and 1 mod
  • Played for over an entire week without real problems
  • More people joined, still at most 5 people online at the same time
  • 1-2 people loading in a higher amount of chunks, others staying still or moving slowly
  • Server crashes and reboots

Be aware that we are not Hostinger support. We don’t provide your server.

Consider dropping settings like the render distance to reduce CPU usage. Fast moving players will cause high CPU usage so you may want to pre-generate parts of the world.

Ok, this is where it took me when opening a ticket via Hostingers Game Panel. Very confusing that it doesn’t lead to Hostingers support in that case.

We provide the game panel that Hostinger use.

Alright, I see. That is not clear what so ever. I’ll see where I can find the correct support system.
