First, nice performance mods. Quite improves the server performance.

Is your feature request related to a problem? Please describe.
Hey,
when the server adjusts the load of the server (e.g. from LOW to NORMAL or NORMAL to Low), it reloads the clients chunks(Which is understandable). Which is quite annoying sometimes.

Describe the solution you'd like
A config key to disable the client reloading of the chunks. So players would need to reload their chunks manually.

Describe alternatives you've considered
A command to reload the chunks would be a good alternative.

Thanks a lot for the report. Unfortunately this by design as soon the "viewdistance" gets adjusted.
You can mitigate the effect by using a higher minViewDistance or mods which avoid the "unloading" of chunks.

There is already a great mod which covers this issue called "Farsight", see:

I will update the mod page to make it clear that farsight is recommend.
