Hello,

I am hosting a CS:GO ZE server and am experiencing lag between rounds. I will post all server specs, server.cfg, and relevant information below after i have explained my situation.

When the player count goes up clients times out for X amount of seconds at round end, depending on how many clients are in the server at the time. It starts at around 10 clients. At 10 ppl it's not too bad, but when it gets over 20+ players it can be really bad where clients can be timing out for 5+ seconds.

Console spams this when round ends:

Those IP's are simply for demonstration, the spam shows actual IP's.

I have googled for endless hours and all people are saying is that it's a form of denial of service. I know for a fact that it isn't as this is too consistent and the patterns for when and how it happens isn't anything like a dos at all.

Some people are saying adding these cvars helps:

Spoiler

sv_occlude_players 0
sv_force_transmit_players 0
net_splitrate 2
occlusion_test_async 0
sv_parallel_packentities 0
sv_parallel_sendsnapshot 1
net_queued_packet_thread 1
net_splitpacket_maxrate 100000
sv_ragdoll_maxcount 1

In addition to this i am running a performance.cfg by having exec performance.cfg in my server.cfg. The performance.cfg looks like this:

sm_cvar vprof_server_thread 1
sm_cvar g_ai_threadedgraphbuild 1

And lastly my server rates (64-Tick server):

Spoiler

sv_maxrate 128000
sv_minrate 30000
sv_maxcmdrate 33
sv_mincmdrate 33
sv_minupdaterate 16
sv_maxupdaterate 16

Nothing of the above helps. I have tried changing cvars, rates, and everything else. Testing the plug-ins one by one will be a little difficult for me considering i need around 10 ppl in the server to be able to replicate the issue.


I am quite certain it has nothing to do with the specs of the machine itself as none of the other servers lags when this happens but i will post a spec list and a sm plugins list below:






Error logs shows nothing of relevancy but can be provided if necessary.

first off you server is not 64 ticks

sv_maxcmdrate 64
sv_mincmdrate 64
sv_minupdaterate 64
sv_maxupdaterate 64

With a -tickrate 64 parameter in the run file it should be 64. It says so in the net graph at least anyway. And i have tried having my rates at 64, that's not where the issue lies at all. It makes no difference, the problem persists regardless of rates and tickrate.

[Johnoclock]

you can try net_maxfilesize 64

Why? That is for people who aren't using fast DL and wants to speed up the download speed for files under 64mb. I have a web server that serves content at much higher speeds.

[Johnoclock]

can i ask when did this happing after you install a new plugin or some els

[ambn]

not sure but maybe a plugin is making your server lag on round_start?
have checked sourcemod plugin's error logs?

[FeelsGoodMan]

@John, it's a little hard to say as i was testing the server with 3-4 ppl max before release. At release it was pretty much finalized so i had no way of narrowing it down any more.

@ambn I am thinking the same thing, but i can't figure out which one. The only thing in the error logs is about a zr stats plug-in that tracks players kill count, infect count, damage dealt etc. It does nothing on round_start.

maybe try to remove one plugin one by one

[FeelsGoodMan]

That will be my next course of action if nobody here are able to help me. I would rather try to avoid that as i would need to test with 10+ ppl in the server after every single plug-in removal.
