I'm using a very small server with most players joining in from other world regions. However, one particular player has began to develop extreme lag (3000+) only after updating the server to 1.21.10. I'm not sure if this is just a coincidence or a culprit as no other player has any similar issue.
Heres the weird part:
- They also have no issue joining on any other server with only about 200 or so ping, and can use any other internet service without issue.
- On different times, their lag returns to how it was before the update.
Server Configurations:
- Entirely using Fabric
- No major or significant mods, mainly optimisation and tweaks like changing minecart and ghast speeds
Has anyone else encountered this problem or know any kind of solution about this?
