Hello, I have a problem with my CS:GO server. From time to time people have lag spikes (high sv / var values). The more people on the server, more often lag spikes appears.

I have Linux Virtual Server.

Server parameters:
Virtualization: OpenVZ
OS: Ubuntu-16.04-x86_64
CPU: Intel Xeon E5 (2.4 Ghz * 4)
RAM: 3072 MB

CS:GO Server:
Gamemode: 1x1 Arena
Max Players: 24
Tickrate: 128

Plugins:
multi1v1.smx
advertisements.smx
mapchooser.smx
drapi_show_damage.smx
basetriggers.smx
rockthevote.smx
nextmap.smx
tidychat.smx
clientprefs.smx

Problem:




Any ideas guys?

Your hardware (specifically CPU) is inadequate to run a 128 tick server with that many players.

I understand you have a correct VPS server?

Not recommended, for game servers the best is a dedicated.

Try this on your server.cfg

//ForceRates
sm_cvar sv_maxrate 128000
sm_cvar sv_minrate 128000
sm_cvar sv_maxcmdrate 128
sm_cvar sv_mincmdrate 128
sm_cvar sv_minupdaterate 128
sm_cvar sv_maxupdaterate 128
sm_cvar net_splitpacket_maxrate 100000
sm_cvar sv_maxunlag 0.5
sm_cvar sv_unlag 1

I have other commands too in my server which have almost same specs.
If i am at home i will edit this post to write those other commands

Thank you guys for quick response! Can you please recommend what kind of hardware specs should I have to run server smoothly? Which is better Linux or Windows?

Thank you very much! I will try these settings tonight. It would be really nice if you could share more your server settings since I was not able to find any recommended.

Those rates will not solve your problem. 24 slots @ 128t on such a slow processor will cause you major var issues regardless.

There is a problem that srcds is not multi-threaded, it uses only one core... Can you please explain for me, how other servers like Zombie Escape with 64 slots can handle it? I mean, of course I will go for better cpu, but with single core I would not be able to go far away?

Thank you.

How many players does this server actually see?

If the CPU speed you've specified is accurate, a full 64 slot server, even @ 64t would suffer tremendous jumps in var.

Sorry, maybe I explained everything in a wrong way. In my case I understand that my single core is too weak to handle 128 tick rate server with 24 players online.

And you mentioned the solution - go for better CPU, I believe that in my case better CPU with 3.4 Ghz would be a solution, but imagine if I would like to go further, from 24 slots to 64 with 128 tick rate. In this case, I believe there is no single core CPU which could withstand such a load?

Basically, the question was how to solve this scalability problem if srcds is not multi threaded?
The only solution would be to migrate to Windows?
Do we have such a strong single core CPU in the market to host a server with 64 slots and 128 tick rate?

Thank you!

>Nononononono, never force a Rate depending on the Tickrate, and also dont force them to have the same min/maxrate! 128 means 128kbs/s, you know someone with a connection that bad? Set the maxrate to 0, its bullsheet to force Players to this.
>Also the mincmd/update Rate should be lower, else Clients will get in trouble when having bad Computers that cant hold up that Tickrate
>Settings sv_unlag is totally useless, its allways enabled and disabling it will never be usefull in any way beside Hacking.
