Hi all,

I'm currently hosting 3 CS:GO servers and everything is running smoothly.

Except when the map changes on one of the servers. It'll use 100% of my CPU for 1-2 seconds to load the new map, and it's causing my two other servers to choke and completely lag out.

Does anyone have any experience with this? How do you run multiple servers on the same OS without it capping out your CPU on map change?

A bit about my setup:

Ryzen 5 2600
16GB RAM
Running Windows Server 2016 OS on physical PC and using Hyper-V to have an Ubuntu server OS where all my CS:GO servers are hosted from.
The Ubuntu server currently has 8 virtual processors assigned and 8GB RAM.

I hope some of you have experienced this before and possibly have a solution for it. I'm considering creating another two VMs (so all CS:GO servers are hosted on their own OS), as this should then prevent the choke, but I hope there's another solution.

Thank you in advance!

may i ask why you are hosting through VM?

The physical server is also hosting a website and database (through another VM) as I was more familiar with the Windows Platform for that kind of thing. That's why I decided to use VMs, so I could still host my game servers on Linux.

I doubt the VM itself is the culprit here, though. I'm guessing I'd have the same issue if I ran ubuntu server on the physical and had the servers hosted there.

are your servers accessing your website / mysql?

Yes, they are accessing the database. But regardless, this isn't really related. The lag only happens when a server changes map.

I've considered assigning the different instances of srcds to specific cores using taskset, but I've been recommended I don't so that. So unless there's something obvious I'm missing, I think I'll just create a VM for each of my srcds instances as that should fix my issues..

Of course it can be related to your database connection.
Please post your sm plugins list output.

[Maxximou5]

If you have any plugins not using threaded queries the scenario you are experiencing is the direct result of a database plugin. If there isn't, then there's something else at work obviously.

a lot of plugins do their saving on map end / on player disconnect which is what happens when map changes

Only SQL heavy one here is SurfTimer.

Looking through my plugins I suddenly suspect the "CSGO Panorama Map Change Crashe Fixer" - I installed this to prevent players' games from crashing, but could this be the reason? That everyone disconnects on mapchange and immediately re-joins?

If we are to say this is the culprit, then how do I get around using this plugin - I can't disable it, cause then my players will have their CS:GO crash every other map..

Here's a link to the plugin: https://forums.alliedmods.net/showthread.php?t=310542

EDIT: Disregard the above. I just tried the command "changelevel surf_meme" in console on an empty server, and the CPU usage still spike to 100% and above causing the other servers to lag.

Does it make any difference, if you change basic map like de_dust2 ?
*edit
Is is workshop map collection ?
