Permanent desync on server during every match

[Spyker 10]

Dear administrators,

I had to create this topic, because I did not find any logical explanation of my problem which is called above. Let me explain its details.

I have one dedicated server (Microsoft Windows Server 2008 R2 Standard 64-bit SP1). Currently there are two servers:

1) Arma 2 server with public warfare mission -> 2302 port

2) Arma 3 server with warfare mission (prototype) -> 2312 port

Every time I notice quite big desync (100k) among all players on Arma 3 server when we try to play our mission.

Here are the details of its appearing:

1) amount of players on Arma 2 server(2302) <20;

2) amount of players on Arma 3 server(2312) <10;

3) amount of bots which can be respawned in game (Arma 3) is up to 30;

4) Arma 3 server fps is between 30-50;

5) Host's load details:

- average cpu load is less than 60%

- average network load is less than 15%

- average HDD load is less than 40%

6) Host hardware specification is:

cpu: Intel Core i5 3570 @ 3.40GHz

motherboard: ASRock H67DE3

HDD: 1863GB Seagate ST2000DM001-1CH164 ATA Device (SATA)

memory: 16.0 GB Dual-Channel DDR3 @ 669MHz (9-9-9-24)

network bandwidth: 100 mbit/s

And server's network config (Arma 3):

MaxMsgSend=512;

MaxSizeGuaranteed=1024;

MaxSizeNonguaranteed=512;

MinBandwidth=16384000;

MaxBandwidth=327680000;

MinErrorToSend=0.008;

MinErrorToSendNear=0.01;

Server's network config (Arma 2):

MaxMsgSend=768;

MaxSizeGuaranteed=1400;

MaxSizeNonguaranteed=700;

MinBandwidth=156160000;

MaxBandwidth=1073741824;

MinErrorToSend=0.0020000001;

MinErrorToSendNear=0.050000001;

class sockets

{

maxPacketSize=1400;

};

If it's possible please tell me what can be the cause of the desync on Arma 3 server. It's weird to see 100k desync even for 2 players on server after bots are respawned on map. And even after the massive respawn desync still exists for 2-5 minutes.

I'd like to admit that desync a littlle bit becomes lower after last Arma 3 update.

Thanks in advance.

Additional information. Server's "monitor" command shows this:

what internet bandwith do you have ? If 100mbits , you can try my config:

MaxMsgSend=16384;

//MaxSizeGuaranteed=256;

//MaxSizeNonguaranteed=128;

MinBandwidth=10485760

MaxBandwidth=104857600;

MinErrorToSend=0.0025;

MinErrorToSendNear=0.01;

MaxCustomFileSize=2920000;

Thanks for your reply and config. I've already tested it. It runs more better but red chain still appears. Concerning "MaxMsgSend" parameter from your config:

Why do set up so big value for it. As I know it should be around 256-512 for warfare modes and <256 for ctf, DM modes.

And why do you comment "MaxSizeGuaranteed" and "MaxSizeNonguaranteed"?

Regards.

without // and smaller maxmsgsend gives me desynch (domination mission with 300-400AIs and 15-20 players), I don't know why but this config gives me no desynch.

I tested your config. No positive results. Still desync can be observed on server. More over it still persists on server when map does not contain any bots. In this case the desync is very small - 200-5000 (max). I've enabled full duplex mode on netwrok adapter and the situation became better. Seems like bis developers can't help me as well. Going to proceed with the investigation alone.
