Optimal Basic.cfg for ARMA2: CO on an 8-Core VDS

[Holmes]

Code: Select all

language="English";
adapter=-1;
3D_Performance=93750;
Resolution_Bpp=32;
Windowed=0;
MinBandwidth=131072;
MaxBandwidth=2147483647;
MaxMsgSend=128;
MaxSizeGuaranteed=512;
MaxSizeNonguaranteed=256;
MinErrorToSend=0.001;
MinErrorToSendNear=0.0099999998;
MaxCustomFileSize=0;

This is what I currently have. We host two 30 slot ARMA2: CO servers that are both full almost 100% of the time. All players experience heavy desync and we have yet to figure out a fix. Any suggestions?

[Edge100x]

Is this a managed or unmanaged VDS?

[Holmes]

Unmanaged

[Edge100x]

It appears that we use this one right now by default:

Code: Select all

MinBandwidth=15000000;
MaxBandwidth=100000000;
MaxMsgSend=1024;
MaxSizeGuaranteed=1024;
MaxSizeNonguaranteed=64;
MinErrorToSend=0.0024999999;
MaxCustomFileSize=0;
Windowed=0;
language="English";
adapter=-1;
3D_Performance=1000000;
Resolution_Bpp=32;

This should hopefully eliminate the majority of the desync? Ill put it into place ASAP and do some testing with it.

[Edge100x]

It's tough to say, since it could also be a setting on your command line or in a different configuration file. If this doesn't help, we can explore those a bit.

[Holmes]

Major desyncing issues are still occuring with that basic.cfg setup that you provided. Below is my current start up line. I use a batch file to start up my server (Almost certain this does not affect performance). The contents of the batch file are below

"C:\r1\arma 2 operation arrowhead\ARMA2OASERVER.exe" "-mod=C:\arma\arma 2;Expansion;ca;@ace;@acex;@acex_ru;@acex_usnavy;@acre;@cba;@cba_a2;@cba_oa;@jayarma2lib_new;@brg_africa;@chn_crocodile;@csj_snake;@ibr_lcivilians;@ibr_plants;@mbg_buildings2;@lingor;@dingor;@anticheat" -cfg=b.cfg -config=p2.cfg -port=151 -bepath=C:\BEServer2

[Holmes]

Anyone have suggestions?

[Edge100x]

There are a some command-line options that you can try, in terms of increasing/decreasing its threading behavior and similar, but I'm not very familiar with them myself. Others who run CO or DayZ may have some more fleshed-out information.

[Holmes]

As I was looking around and doing some research (I assumed it was the case) it has nothing to do with network connectivity but hardware itself. Im running an 8 core vds so my only other option is to upgrade to a full machine which I gather would have no issues running my two servers. If there is a way to optimize the 8 core vds for a good bit until I have the finances, someone please share

[IcEWoLF]

I don't think 8 HT cores are good enough for this.
You will have better luck with 8 physical cores with Arma2.

[Edge100x]

IcEWoLF, ArmA2 actually runs very well on VDSes, and in most cases the HT cores here have similar performance to physical cores (due to how much the machines are underloaded). But, dedicated hardware would be a little faster, potentially.

Holmes, can you confirm that you're seeing CPU usage problems by looking at the process in the task manager?

More cores might actually not help in your case if it is leading to ping-ponging. Are the cores showing that the process is being moved around quite a bit?

Have you tried with fewer threads?

[Holmes]

CPU Usage doesn't seem to be the problem. Usage never goes above 35%.

[Edge100x]

35% is very high overall, certainly.

35% could mean slightly less than 3 full cores are in use at 100% (hitting 100% will cause clear performance problems), or it could mean more cores are being used to at less than 100% each and some more complicated threading/locking issues are at play. On the latter, have you tested the server with just one or two cores?

[Holmes]

I have no yet no. Ill try setting it to two cores per server and see how it performs
