Dedicated server performance

[franklin]

I'm using the following currently, and get little spells of lag from time to time when running 3 servers off the box. We shut down the 4th because it causes too much lag until I can figure out some better settings (and I'm not sure what to do). Also cant find good documentation on how to run the server as beta, other than overwriting the .exe directly.

language="English";
Windowed=0;
adapter=-1;
3D_Performance=1;
Resolution_Bpp=32;
MinBandwidth=92160000;
MaxBandwidth=100000000;
MaxMsgSend=36;
MaxSizeGuaranteed=1200;
MaxSizeNonguaranteed=600;
MinErrorToSend=0.001;
MinErrorToSendNear=0.0099999998;
MaxCustomFileSize=0;

arma2oaserver.exe -mod=Expansion\beta;Expansion\beta\Expansion ... etc or simply run server from arma2\Expansion\Beta\arma2oaserver.exe

HOW TO INSTALL AND RUN THE BETA PATCH ------------------------------------------------------------------------

Run the patch exe to apply the patch setup automatically (you may be prompted to choose your exact version in some occasions).

* It will install all beta content to a mod folder "Expansion\Beta", including the beta exe (that has to be run properly with working directory set to the main game installation, see below for more information)

* To launch Arma2 Operation Arrowhead beta patch you need to go to the main game directory and click on shortcut "Launch Arma2 OA Beta Patch"

* You can configure your Arma2 OA with Beta Patch including other mods etc., just make make sure that: in your ArmA Shortcut start-up Target line;

- You are running the Arma2OA.exe from your "Expansion\beta" folder.

- You have "Expansion\beta;Expansion\beta\Expansion" in your modfolder as in

- You have "Expansion\beta;Expansion\beta\Expansion" in your modfolder as in
-mod=Expansion\beta;Expansion\beta\Expansion
example: "C:\Program Files\Bohemia Interactive\ARMA 2 Operation Arrowhead\Expansion\beta\arma2OA.exe"
-mod=Expansion\beta;Expansion\beta\Expansion

- Make sure the shortcut's "Start In" section refers to main "ARMA 2 Operation Arrowhead" main working folder
and NOT "ARMA 2 Operation Arrowhead/beta"
example: "C:\Program Files\Bohemia Interactive\ARMA 2 Operation Arrowhead"

You can always run your Arma2 OA final version in the main Arma2 OA folder if you use default application shortcuts, start menu or run the regular arma2OA.exe without the beta mod folder.

OK, this is starting to piss me off as a server manager ..
A Octo Core server with 16 GB Ram is having huge fps drops with 10 - 7 players(FPS is around 37-27 - Max peek 47, very rare) and I have configured it the best way I can by reading here.

Our cfg:

MaxBandwidth=1000000000;//Added it to 1GB as the server won't never reach 1GB since our switch port is on 100MBit
MaxMsgSend=128;
MaxSizeGuaranteed=1024;
MaxSizeNonguaranteed=256;
MinErrorToSend=0.001;
MinErrorToSendNear=0.001;
MaxCustomFileSize=90000;
Windowed=0;
language="English";
adapter=-1;
3D_Performance=8021;
Resolution_W=160;
Resolution_H=120;
Resolution_Bpp=32;

I removed minbandwith as I read from someone that Suma said its proper set already so no need to set it.

Your minErrorToSendNear value is way too low. I would suggest increasing it to 0.01, perhaps slightly higher (I tested as high as 0.05 with good results).

Alright, I will try that


Update:
Alright, I put on warfare with AI enabled and the FPS went from 50 (6 players ) to 10 - 12 when we had 10 players ..

Any ideas?

Yes AI can pretty much pegg your processor. Its all depending on your mission scripting/setup and raw power of you dedicated server machine.

I was running warfare too and noticed the same thing, or mostly the same. We didnt have had so low fps ( our went down to 30 lowest ) but if I turn of some AI realted features it runs much better. I have i5 @ 2,8Ghz / 16gb ram / 100Mbit and I run only one OA|CO server. My settings are page back.

Thing is I am running a Octo core at 2.4Ghz each core & 16 GB Ram with CPUCount 8 as launch parameter .. and I still find it pretty much "stupid" that fps is dropping at 10 ..

Digging out the old thread.
Try to leave the cfg empty, meaning:

language="English";
adapter=-1;
3D_Performance=93750;
Resolution_Bpp=32;
MaxCustomFileSize=0;
Windowed=0;

What I found after zillion versions of cfg was server worked best with no bandwidth configuration at all.
I know how silly it may read but hey, what can I do. That's what we found being hosted by JestServers - maybe their machines are so uber they don't need no cfgs.
Seems like it.

+1 on a dedicated linux server

"cpucount=8" means nothing if the dedicated server mainly utilize two threads (at least from info from other server admins on this forum). Your limitation is speed of the cpu.
