Hello.
Recently we've got us a new dedicated server, and it's pretty decent:
cpu E3-1241v2, 32GB RAM
2x 240GB Intel SSD
1gbit network

We're currently running Debian 8 (64bit).

We have one really annoying problem and that is when round reaches end (ends by itself) or in random case, when player gets killed.
Server is configured to be run as 128tick competitive server, without any extra plugins (just default SM 1.8 plugins)

I was monitoring it in-game and there is no loss or choke, and I've noticed that some of lines on the graph are getting really high at the time of the lag (to be more precise, it freezes up for around a 0.5s and teleports the players back a few steps).

Here is some of the information you may need.

I've been monitoring the network traffic (and it's around 4mbps) and CPU/RAM consumption, and CPU usage iis always below 40%, ram usage is always below 1GB.
It happens regardless of the player count (let it be 10 players, or just two, it's the same).
What would you recommend us to do?
And if there is something that needs to be done on the OS level, please, tell me, 'cause I really can't find the cause of this problem.

Have you disable Intel Hyper Threading ? It split one core to two threats...
And are you sure your server not run power safe mode, processor running lower GHz ?

Hi, thank you for your answer.
No, I didn't disable Hyper threading, since it works properly on the dedicated server hosted in France (almost the same configuration, cpu is just a bit older).


I may have an idea when this occures, but nothing solid.
It happens mostly when net_graph (set to 3) shows a large spike, with number of bytes around 1400+.
It looks something like this:

Oh and, I'm sorry for posting in the wrong section, so if anyone can move it to srcds servers, it would be nice

[Bacardi]

Can you show what all kind settings/cvars you have change, inside seever.cfg

What valve wiki mention, red verticals below tells, you are not gain all packets from server. Packets are dropping.

And this is not same as CHOKE were server wait before sending next packets, happens when player rate is small and updaterate high.

Can you PM ip to your server, if I go quick visit there some point? I'm blind

edit:
I've contacted one of my friends from Serbian ISP (Verat.net) and he told me that only thing that can cause a problem like this can be on the network itself (with the data I've given to him).
He told me first to check the MTU value, which I did, and I increased it to 9000, but it didn't help. He then told me that it must be hardcoded setting on their switch/router in the DC itself and that we as clients can't do anything about it.

I also tried to disable hyper threading before I contacted my friend, but it didn't help.
Also I've tried to run it on single core (setting affinity) and setting high priority, but none of the settings did anything.

What I quick visit in your server, it look running well, expect there are somekind delay, kind wierd one.
You can notice when you shoot a bot, bullet hits after very small delay.
And net_graph not show any LOSS or CHOKE :/

Maybe had something to do network.

That's right, it has something to do with network, and our dedicated server provider won't do anything about it...

You can PM me if you wish. I'm willing to take a look as a I'm an Network Engineer..

Thank you very much, I appreciate your will to help, but we've already cancelled our server
They returned us our money and we'll probably order a new server hosted in Frankfurt, just to be safe
