Random super high ping lag spikes with solid 20 TPS. No idea what is causing them.
So intermittently we will get a huge lag spike on the server. Most players pings will shoot up to 300+ and sometimes even 1000+. This lasts about 30 seconds and slowly goes down over time. We have rubberbanding issues. All while the TPS is locked at a solid 20.
Some Info
- Server CPU: 3 Threads of 7950x
- Ram: 8GB
- Players: Usually around 3-8 (issue gets worse with more players online)
- Server Version: Purpur 1.21.1-2329-803bf62 (MC: 1.21.1)*
Troubleshooting I've Tried
- Lowering render distance
- Continuously pinging the server while the server is lagging in-game with command prompt. Command prompt stays at a solid 50ms ping for me while in-game it shoots up to 500+.
- We tried moving our server to a different location with the same host
- Tried a different host with the same CPU (7950x). Same issues.

I can't figure out what is going on. Is the only solution to just try to start testing if removing plugins one by one solves the issue? Are there any troubleshooting steps that I am missing or does anyone have any ideas what's going on?
