Details of the issue I am playing SkyFactory 3 on a server a friend is hosting at his home.

Whenever the chunks containing most of my power generation and ore processing are loaded, the receiving bandwidth usage goes up to ~2 Mbit/s. This wouldn't be a problem for me, but it caps out my friends upload rate, so the server lags a lot.

Here's a screenshot of the mentioned area:

When looking at it from the other side of the base and letting the chunks unload, the data rate drops to about 200Kbit/s, so it's most definitely an issue with one of the mods i used in the ore processing/power generation area:

A list of the mods and used blocks that could be part of the issue:
- Refined Storage (Importers, Exporters, External Storage, Crafters, Solderers, Controller, Grids)
- EnderIO (Item conduit, power conduit, pressurized fluid conduit, SAG Mill, Alloy Smelter, Item Buffer, Enchanter, power bank)
- RFTools (Crafter)
- Storage Drawers (Compacting drawers, drawer controller)
- Ex Nihilo Adscensio (Crucibles)
- Ex Nihilo Compressum (Auto Heavy Sieve, Auto Compressed Hammer)
- Environmental Tech (Tier 3 Solar Array)
- Tiny Progressions (Cobblestone generator)

None of the machines (except the refined storage system) were active when i took the screenshot.

I didn't provide a log file because between joining and leaving the server nothing is logged.

Any idea what could be the cause?

Your friends bad upload.

There's a few things to render in that area = server needs to send to client.

It's prob not needed, but there's always logs and they are found here:

/logs/fml-server-latest.log <--- that's the server log

And instructions for getting log from client is found here:

Regardless of the upload rate, a bandwidth usage of 2Mbit/s for one player is far too much for one player with only this small a base.

Anyway, I found out Ex Nihilo barrels, or an interaction between them and EnderIO/ExtraUtils2 pipes, were the cause of the problem. After removing them, the bandwidth usage went down to ~150kbit/s.
