Bandwidth issue 100kbps -> 2000kbps

[doomguy4]

When I use AM2 on my server with the following other mods bandwidth per user increases from ~150kbps to ~2000kbps

I have tested and confirmed this by removing AM2 seeing bandwidth drop then adding it back again and seeing it rise

Is the bandwidth increase present with just AM2 installed? Helps to know if it's specific to AM2 or if it's a mod interaction issue.

[doomguy4]

With only AM2 and animation API Bandwidth it normal.
Here is a link to the private modpack I am using (its 160MB)
http://www.humenet.net/Minecraft/HumeMod1710k.zip

[jjtParadox]

Hmm so some combination is causing bandwidth issues... What are you using to measure bandwidth?

[doomguy4]

I am using Task Manager
Here is an image of the bandwidth issue http://www.humenet.net/Minecraft/Minecraft73468.png
New is with AM2, Old is without AM2

It fluctuates so much in New because I am hitting the upload bandwidth cap on my connection which causes a Netty exception when connection from outside, when connecting locally it is not an issue.

[LemADEC]

did you check with Opis which packets are using up the bandwidth?
do you have a clean world with other mods blocks/entities nearby when testing?
Can you try without the ItemPhysic, Reika's and Opis mods (including their related libraries)?

[jjtParadox]

This has most likely been resolved by #1348, but if it's still an issue we can still work on this.

[LemADEC]

yes, you can close this one, if it still happens we'll need fresh logs anyway :)

[jjtParadox]

@kolatra could you close this one?
