Fix server performance

Problem Description


I have made a server with a small modpack, mainly containing QOL mods nothing big, and with only 1 player online TPS is very low (ranges from 8-13 rarely being at 20) and ram usage is around 6.5 with only one player online.

Reproduction Steps

  • Start server
  • Load client
  • join server

Some mods just run really poorly on servers. Your best bet it to install the Spark mod on the server and run a profiler to see what mods could be causing the issue.
