Hi Delvr,

Yesterday while testing a pack I was putting together we noticed extreme server thread lag.
I made a small video so you can get a feel for what was being experienced here.

After doing some profiling on the server thread me and few other mod devs came to the conclusion that the issue was run away chunk generation.
Here is the VisualVM sampler snapshot

I need to be clear here that your mod was not the only mod contributing to this but it did play a major part. There was massive improvement to the stack overflow issues the server thread was experiencing after disabling streams.

I am posting here to encourage you to make sure that streams is not loading new chunks during worldgen. I hope this has been helpful.

Streams 1.11-0.3
Farseek 1.11-2.1
MC 1.11.2
Forge 13.20.0.2228

Yeah I imagine that it showing up in the Entities is the side effect of it being a stack overflow in the server thread specificly and that entites just happen to be the most dynamic object handled by that thread and thus readily the most visual.

Thanks for taking a look Delvr

Hi Rosethorns,

thanks for reporting this. From the video I'm a bit surprised to see specific lag in entity updates rather than in terrain generation when moving, but I'll take a look.

Which version of Minecraft and Farseek/Streams are you using?

I've been hearing other reports about this issue and will prioritize it. Please follow issue delvr/Farseek#22 for updates.
