Optimizing Fabric for Public Server or switching to Paper/Pufferfish?
Hello Reader and Gamer,
I'm reaching out for some advice regarding our Java Minecraft server, which has been running for over 4 years. Here are some details about our current situation:
- We've used Purpur and Paper throughout our server's history, but recently many players have requested we switch to Fabric due to Paper disabling a lot of redstone and making farming difficult.
- We just started a new season on 1.21 running Fabric, but we've been struggling to maintain a consistent TPS, often not even reaching 15.
- Our server consistently hosts over 15 players, though we expect this number to drop to 5-10 in the next six months.
- We recently upgraded our RAM from 8GB to 12GB, with 9GB allocated to startup.
- Most of our mods are performance-based and moderation-based, with a few random ones like fsit.
- We also have a couple of datapacks and custom ones to replace some of the features we had while on Paper/Purpur.
- We used to have a daily restart enabled but there are no commands to restart or start a server on Fabric. So we've been seeing an issue if the server does stop or crash, then there is a rollback. We've tried kicking all the players before the server stops, but this doesn't seem like a long term solution.
- Here is our Spark Profiler link: https://spark.lucko.me/M0DxvlWYUu
We're torn between continuing with Fabric and trying to optimize for a stable 20 TPS or reverting to Paper/PurPur/Pufferfish. Fabric has been a significant challenge for our staff team, with a steep learning curve and many new commands and replacements to figure out. We've invested a lot of time into creating the server on Fabric, but we couldn't stress test it until day one, leaving us at a sunk cost fallacy decision point.
Any help or insight from others who have faced similar challenges would be greatly appreciated!
Thank you!

Restart takes a long time
Ever since we updated our server to 1.20+, its been taking about 15 minutes for the server to fully restart. Before it took only a few seconds to a minute or two.
What are some possible reasons? (Sorry I am still learning about server management and inherited the server)
Startup Command

OOM Kill need help with startup configuring
Just updated server to 1.20.1 and been having problems running out of memory. Thinking it has to do with startup parameters. Not sure the steps to fix it.
Currently: java -Xms4400M -Xmx4400M -jar purpur-1.20.1-2016.jar
