[1.19.2] Huge lag spikes while travelling in The End and other dimensions. #89

Closed Gbergz closed 1 year ago

Describe the bug There's huge lag spikes while travelling around in The End and other dimensions.

To Reproduce [hopefully] Steps to reproduce the behavior:

  1. Start flying in any direction
  2. Keep flying
  3. Lag spike start and world stops generating.
  4. Spike lasts around 1 minute maybe 1 and a half.
  5. World resumes, no lag spike.
  6. Repeats after awhile.
  7. Profit.

Expected behavior That the lag spike doesn't happen and I can continue generating land.

Spark Profiler I've included a spark profiler which I ran through the lag spikes, it shows "essentials" taking up 54% of the servers performance, which is not normal. Link: https://spark.lucko.me/GyR1BG5uhu

Additional context I am in a modpack This started recently and I've not experienced it before, thought it maybe was caused by an update to the mod, but it hasn't updated in awhile, so I am not sure...

After some research, it might not be this mod afterall. Apologies.

I think you were right the first time. I've optimized the offending code; turns out the checks Essentials does for if endermen should be allowed to teleport are quite laggy when you're travelling in a dimension with hundreds of them. It'll be fixed in the next version.
