• Custom Events in the Blocky World: Using JFR in Minecraft
  1 project | news.ycombinator.com | 28 Nov 2023

  I'm not sure how much of the built in JFR a mod for Minecraft called Spark uses but it is a fairly common tool for debugging and visualising lag on modded servers https://spark.lucko.me/

• Help with paper server lag
  1 project | /r/admincraft | 11 Jun 2023

  You should run the Spark profiler and come back here with the result.

• Plugin to detect laggy/lag causing chunks? [HELP]
  1 project | /r/admincraft | 1 Jun 2023

  Use spark. It should come preinstalled with PurpurMC.

• [To Oracle cloud users] Performance issues on a free tier ampere instance. Is it normal?
  1 project | /r/admincraft | 31 May 2023

  Got a spark report? These reports can help you figure out what's taking the most time in your tick loop.

• Optimising a PC for hosting a Minecraft server
  1 project | /r/admincraft | 22 May 2023

  Lowering your simulation distance will probably help quite a bit -- 12 is quite large. If you're running on 1.19, villagers may be a source of lag, however, I would first check with spark to see what specifically is causing lag.

• 1FPS after few minutes in a world.
  1 project | /r/feedthebeast | 14 May 2023

  I would take the debug piechart with a grain of salt (it's very easy for mods to get it into a messed up state where a section is opened but not closed, miscategorizing all the events that happen after it). The best profiler is spark. When you experience performance issues, do a spark profile for a minute or two

• How do i know what mod is makes my modpack ultra slow/heavy?
  1 project | /r/feedthebeast | 30 Apr 2023

  You can use something like spark to try and diagnose the issue, although I think it’s kinda complex.
