I have notice these lines on config/forge.cfg

 

general {

    # Controls the number threshold at which Packet51 is preferred over Packet52, default and minimum 64, maximum 1024

    I:clumpingThreshold=64

    B:enableGlobalConfig=false

}

 

Is there any wiki or something like that where I can find info about clumpingThreshold setting? Does anyone knows why it works?

 

Someone should write up a note about it eventually.

Basically, when MC sends updates to clients it does it in 2 ways:

1) It sends JUST what was changed

2) It resends the entire chunk

 

Resending the entire chunk is costly, esp if you have many many tile entities.

This config option is there to allow server admins to fiddle with this number.

If you're a server admin, and you see a lot of your traffic going through just file tile entities of full work chunks, then you should set this threshold to larger.

 

Its a little tweak that should be used at a server owners descression to try and tune there network use.
