headless server is laggy

[CoNfu5eD]

Hello everyone,

I installed a headless factorio server (Version 1.1.80 - linux64) on my ubuntu VPS.

Server

CPU: 10 vCores (cpu)
Memory: 48GB (ram)
Space: 800GB (ssd)
Network: Sync - 500Mbit/s (fix) up to 1Gbit/s (flex)
OS: Ubuntu 20.04.3
IPS: Strato (German IPS)


The Server is ment for me and up to 4 friends to play on it, but it is lagging already when just one player is online.
We currently play a redmew spiral map, that is running flawless if hostet in a normal game session for multiple players.
But we wanted a headless server hosted remotely so each of us can play any time with or without the others..

Install guide I used (from wiki): https://wiki.factorio.com/Multiplayer#S ... rio_server



What I tried so far..

- I already monitored the hardware and network load with glances (terminal tool)
and network is only at like 20-30Kb/s while on the hardware there is like 5% CPU and like 1.5GB of RAM used.

- I tried various settings for the "max_heartbeats_per_second" setting like (30, 100, 120, 240, 60) - no change at all..

- I also tried stopping all other services on the server (webhosting, other gameserver) without any improvement..

- I also disabled the server firewall for testing but also no improvement there..

So I wonder what the problem could be..

I hope some of you have Ideas what is going on, because I already run out of ideas for now.


Sorry for my bad english (I hope you can understand it),

Hi,
thanks for the quick reply.

I hope those files are what you wanted me to post.

I'd don't see anything that suggests lagging, can you explain in detail what it feels like and when it happens?

[CoNfu5eD]

While walking over the map it feels smooth and in the next moment you are increasingly slowed down with stuttering in the movement (FPS stay at ~ 60).
Sometimes it happens just a little, but sometimes it slows you down till it stops you from moving for something like a second after that the game continues smooth for some time (seconds) until it happens again.

Same on the map-view when zoomed out, like everything where the view is moved.

Feels like the game can not render the view fast enough and locks up..

I have a similar performance problem (I'm using headless server on ubuntu 18.04, E5-2698v3, 128G RAM, 50Mbps Uploads), check the FPS/UPS on the client, its always 60/60, but the character cannot move smoothy and everything just slow down. Save the map and create server at local client will be very smoothy, everything is ok

And I found that if there are more players online, the problem will be more serious. Is this a clients-server sync problem or something? Looks like a player who has bad network environment join the server will slow all player down.
For give my poor Eng.
