Hi guys,

I am hosting a 100 slot server on a hosted Dedicated Server.

The specs are:
CPU: Intel i7-7700K
RAM: 64GB DDR4 2400MHz
Storage: SoftRaid 2X450GB NVMe
Network: 1Gbps, 250mbps outgoing bandwith

I'm noticing a lot of lag throughout the server restart cycle. Currently restarting every 6-8 hours. It's modded with all your usual mods (Kits, 5x, Qsmelt, BetterLoot, StackSize+, Instant Craft) - so I can understand having all the mods will affect performance a bit.

Even with the server having low players (10-20 players) every now and then it still rubber bands, and occasionally a group of players will get kicked with the following error: Packet Flooding: Player Tick

Any ideas on what could be causing this?

One of the reason that happens, is when something heavy happens (Ex: on my test server i have cleanup script that checks and removes 10-20k entities)

Can you please provide us a full list of installed plugins?

The mods I have installed are:
BetterLoot (nothing too drastic in terms of the extra loot)
Building Grade
Crafting Controller
Death Notes
Gather Manager
Info Panel
Kits
NTeleportation
QuickSmelt
RemoverTool
StackSizeController

It seems to only happen occasionally, earlier today it did it twice within about 20 minutes, but now with 30 players on there has been no lag in about 6 hours..

Save interval is set to 5 minutes, and entity count is only at 36,500 due to wipe today.

Could you please provide us the output of `o.plugins` ?

Going on 8 hours now though, and haven't had any noticable issues.

Also, someone can drop a lot of items (with worldmodel), like Building Plans or rocks. I can recommend you to use

https://umod.org/plugins/ignore-collision

and block instant crafting of rocks and building plans with hammers

Appreciate the help guys, I will give it a go tomorrow if the issue presents itself again. Thanks.
