      Description update by IonicEcko

      I'm going to use this one as a master for the performance degradation experienced in BDS on a Linux install post 1.14. I've done my best to summarise the info provided in this ticket and others but please feel free to comment below if you have further info.

      What is happening?
      It appears that post 1.14, CPU usage on linux is far higher than the 1.13 releases. Testing against identical kit using Windows vs Linux yields far better performance on Windows than on Linux

      How to reproduce

      1. Build Linux box on Ubuntu 18.04 LTS (per last published Sys Reqs).
      2. Create new server using default properties file.
      3. Load into the world and note significantly higher CPU utilization than a Windows equivalent. Even with only 1 active player.

      Notes from community members

      • World (chunk) generation appears to contribute to the slowness. Logging into a new box the CPU pinning seems to occur while chunks are generating and falls off over time.
      • Chunk generation appears slow to the player. (the view distance expands slowly)
      • While under load, server time is obviously affected causing numerous issues for players,
      • Was not present in the 1.13 releases.
      • Does not appear to have improved with the subsequent 1.14 releases.


      Issue with CPU maxing out to 100% usage when having a single client connected to dedicated bedrock server on Linux/Windows server.  Testing environment including Ubuntu 18.04 LTS with 1 physical box (Celeron CPU 1007U @ 1.50 GHz 2 core ) and Azure Standard D2s v3 hosted VM.).

      When server is idle with no connections, CPU is perfectly fine.

      Java server has no adverse affect on connections and performance is much better.  Is this typical?
