CPU usage and terrible lag.

Running on a linux platform. I run the latest version of manimod, sharedbans, StatsmeMinimum-Plugin. Tickrate 100, 28 player server up at a host by the name of mammothgames.

Lately I've noticed TERRIBLE lag. So I've run rcon stats command to see if I can see anything noticable.

Here's what it reports..

CPU....... In..............Out.............Uptime....Users... FPS.........Players
64.75......3972.45....9432.80......15...........0. ........60.96......11

Does any body know what could be causing this? Is any one else having this problem. Can any one tell me a way to fix this?

I thought that it could be a problem that's a result of one of the mods or maps we have.. But I don't think so. We just put up another server that has a fresh install with the latest version of manimod only. It reports the same thing and has the same exact problem : (

You need a super computer just to run srcds. In fact there is no server right now that can run srcds.

try without manimod then? Or maybe the server just cant handle 28 players with that high tickrate?

28 players with a 100 tickrate requires IMMENSE power, even a 3.0GHz Xeon couldn't handle that. I recommend decreasing your players to 24 with a 66 tickrate, or 20 players with a 100 tickrate.

How IMMENSE?

I've done 24 players @ 100tick on a single processor Intel system, runs high on processor load. I would personally recommend AMD if you're going to go for a hosting rig. You can fit alot more on the AMD than you can on the Intel system. I'm not sure if it's the HT, you could try turning HT off and seeing how it performs.

Same issue here, we usually run 2 1.3 and 2 source servers and noticed since the update terribly "jerky" gameplay and occasional big spikes that drop half the players, tried just one source with no plugins on there and still the same.

1. FPS === Tickrate, Your server was only managing to hold 60fps, which is less than the 100 you should have for a 100 tick server
   
2. SRCDS has a horrible memory leak which means that if it is not restarted every so often it eats up all available memory causing the server to use the swap, and thus lag.
   
   An "rcon quit" to restart the server should free up the memory. However once it hits the swap I like to do a full server restart to get rid of any swap usage (just a preference)

and once again I pimp whisper and his stuff on serverwiki.org on getting your server setup properly...

What flavor of linux is on the box?
As as flash477 pointed out your box is not holding the fps... the problem there is that you need to have a linux kernel timer set at 1000 and not at the current default of 250 (maybe lower, I do not know if any of the distro's are going lower)

The max server FPS you will see on a linux box as about 334

Ah good move trying a fresh install. I thought it might have been one of the mods I was using. I had the latest of (primary) manismod, the latest in (just for redirect)beetlesmod, sharedbans, vipmod, and hlstatsx for stats all installed. I've had service through a host called mammothgames for a couple years now and things have been fine. They upgraded the control panel they use and needed to move me to a different computer because of it. Pluss it was starting to have problems.

So 1 ip address and a different computer later, I type rcon stats at the HLSW console and it says with 25 people playing that the processor is running at 99% of its processing ability. We all know what that leads to... Any way, I used the control panel that came with the new server to completely reinstall and wipe out all mods and test again. Guess what? Same problem. Either mammothgames has a virus, or the last steam update hosed our linux dedicated servers. The only thing that I can think of as a fix for it now is what's mentioned about Kernel Timer Frequency. I can't get those guys to process what "Kernel Timer Frequency" means though.. I think their just putting me off because of some (X variable they don't want to share with me lol)

I know they said FC something.. I'm assuming that's Fedora Core. They said it was either version 24, 28, or 29. Not sure. I'll ask if I don't just change hosts.

TY ALL for the help and responses. I'll be keeping an eye on this post as I'd like to see if others are experiencing a problem as well.

STEAM, you've been yelled at enough by the world. I won't play the blame game. J/K ^_^

Apparently a while back loads were much better, and now since updates it's just gotten worse and worse.

How come valve dont admit they messed something up and at least try to fix it ? this is just crazy, how will people run their gaming servers!!

[NitOxYs]

Recompile your kernel, get rid of the slack, and a 20 man full pub 100tick and gungame mods takes up around 45% cpu.

[Colster]

Thats still pretty extreme given that most GSP's would look to run 4 servers on the spec I gave above

[NitOxYs]

I actually limit 4 source servers per box.
