ded server minimum specs

[Peterson 10]

Would a Pentium D 2.8 1gb RAM run a 32slot pub?

I am looking at buying a 1U and having it colocated. Just curious as to how low I can go. I would ultimately like to run a 40-64 player.

Im running a quad core budddy with 4 gig and tbh would not go for anything lower.....

I doubt if mine would run a 40 - 64 player though.... mind you, never tried it....

[Peterson 10]

well I currently run a Q9300 dedicated and I run 3 64slot servers...

I am looking to downgrade as I do not need that much power

[Taxman 10]

And ?

buddy.. I just tried to answer your question, wasnt trying to say "I had a bigger one than you" Doh!

Nm.... buy yourself a pentium and try it out....

[Peterson 10]

I am not running this on a personal computer. This is colocated dedicated server on 1gigabit network.

I am new to ArmA and just curious what will run a medium sized server

[Taxman 10]

and you think I would even state that I had a dedi,,, if it wasnt a dedicated ?

my hope pc.. is nothing to do with my dedicated.

nM... Ignore my attempt to help you by giving you a comparison and wait for the next person who may post....

[Peterson 10]

you havn't provided me with anything useful at all... If I can run 3 off my current setup and you can't run 1 then something is wrong there.

[Taxman 10]

who said i couldnt run one.. ? I am running one.. but im using a quad core 2.66 4 gig ram, I am currently using it for a 24 man Pvp arma server nothing else running on it.. except TS 3... like I said in my first post.. I would not go lower than that spec.... if thatn is not useful then please do as I said buy yourself a pentium with 1 gig of ram and Enjoy the Lag...

YOU said you are new to arma......... then what are you running off your server at present ?....

---------- Post added at 12:54 ---------- Previous post was at 12:53 ----------

BTW I have it set at 24 for a reason.... It can obviously run more.. but wouldnt think it would go above 32 without losing some of the performance...

Our old server was an AMD single core 3800+ with 1GB of ram on Win 2003 x64; it did us proud for a year and a half with 30 player coop's and 60 player pvp's, it did max out the cpu @ 100% load so there's your minuim spec right there. Run a nice tight server install, keep your server services optimised and make sure your on a good network (100MB). Yes a Pentium D 2.8 1gb RAM would run a 32 slot public, I ran one at Multiplay i37 last year which was internet facing too.

I would like to run a dedicated linux server with the highest population and best performance possible. This is a server hardware specs thread, so I will leave topics related to networking for another time.

I have lots of speculation, but no evidence, so everything that follows is just a guess. I am looking for advice based on actual experience / test results / inside knowledge of the server code.

The hardware considerations I think are important are:

1. CPU clock speed

I believe this will be most important. I am considering dual core instead of quad core because I can OC to a higher clock rate on dual core.

2. CPU number of cores

I believe number of cores is less important than clock speed. I have read test results which indicate that only one core gets fully utilized by the server and any others are only marginally utilized. I will go with dual or possibly 4 cores, but I have no evidence that more than 4 cores will be of value at all.

3. CPU Cache size

I expect that the larger the cache the better in this case. This will be a big influence on the CPU(s) I select.

4. Amount of RAM

I have read that a single game instance will never take more than 3GB RAM no matter how many players or how much AI. I would like a better way to predict amount of RAM needed for a given instance.

5. Speed of RAM

My expectation is that blazing fast RAM is not actually useful. Having a large CPU cache is much more important. I am planning to buy reliable but possibly slower RAM based on this expectation.

6. Disk IO

I expect disk IO to be modest at best.

7. Graphics

I expect only needing console access for administration.

8. Hyper Threading

I believe this is of no value and should be turned off.

Can anyone comment on my speculation and replace it with evidence of fact?

Thanks

[Taxman 10]

I would be interested in this also...

CPU core I suppose where the quad comes in most useful is if you wish to run more than one server.... running them as a service and locking them to individual cores is useful......

all other questions I await for someone that knows best. :)

4. Amount of RAM

I have read that a single game instance will never take more than 3GB RAM no matter how many players or how much AI. I would like a better way to predict amount of RAM needed for a given instance.

From my experience my Arma2 linux server never used more then 500MB of RAM for its process. I was watching top-stats when playing some WarfareBE games during server tweaking. I was using ACE2 and ZeusAI mods and there were 3 players + some 29AI to fill WarfareBE slots.

Good info there thanks. Just what i needed to hear.

Since im buying a new PC now im making this older one ready for dedi. I will not spend tons of cash but install AMD quad and 4GB ram into it. Plus i will turn on the 100mb network when i do. Never had a server so i wouldnt know how to set it all up, but im sure someone around here can help when the time is right. :)

Nice to know it wont be for 6-8 people only wich i thaught at first lol. Imagined i had to go mega-brutus-mongo hardware to run 20 slots. All feels good now.

EDIT: What upload speed is needed for around 20 slots? Is 10Mbit/s enough? Wonder wich i have to order as it would be nice if 100/10 would be enough.

Somethink like a dualcore e8400 will run fine for any mission. Iv had many servers and if you only plan on runing 1 server then you dont need a quad server and thats a fact. Because arma 2 doesnt even come close to using 2cores let alone 4cores.

At the moment i have a i7 860 oc @ 3.4ghz and our warfare servers uses around 35% cpu out of 100% so i just set 1 arma server to 2cores which is 50%

I also had an e8400 @ 4.0ghz on arma not arma 2 and there was no fps inprovement on the 32 player warfare mission we run. E8400 @ 3.0ghz vs e8400 4.0ghz just preformed the same. Its like this game doesnt use the extra oc for better proformance. same as it doesnt use 4cores to give better server fps

[ball0fire 10]

if thats the case

what would cause low fps for a server?

i mean like 5fps in a 30 player slot warfare mission

its running on a quad cored SUN server (at least 3 dedicated cores) with i dont know how much bandwith, lets just say as good as yah can get.

once the player count gets to aboot 12, server fps starts dropping from initial low 40's all the way down to 5 fps once full

we used the basic server config that Jman posted from the kellys heroes site/ thread

any thoughts?

or should have i started a new thread in the multiplayer section for this, in that case can this post be moved?

I've got 3 servers running using the following specs

1) Intel Xeon 3.06GHz, 2GB RAM, XP Professional SP3, 100MB (1-to-1 connection)

2) Dual Intel Xeon 2.80GHz (with Hyper-Threading), 2GB RAM, XP Professional SP3, 100MB (1-to-1 connection)

3) Intel Core2 Duo E6600 2.4GHz, 4GB RAM, XP Professional SP3, 100MB (1-to-1 connection)

The first 2 are on-loan to an ARMA II British Co-op Squad (Romeo 2.5 www.romeo25.com), and to my knowledge both run fine (We've had a Joint OP on one of them with around 50 folks, which I did encounter sporadic moments of lag but mainly at the beginning when everyone was joining) - Both systems are setup for 64players

The third is run for the gaming squad I participate with (Volcbat - www.volcbat.com) and is setup for 64 players, and so far I've not encountered any issues with it.

One point to note is that the 3 systems are connected to a pure 100MB Internet connection, so bandwidth isn't an issue :)

[terox 316]

we run a xeon x5570 with hyperthreading, 6gb ram and are colocated

We can easily accomodate 3 arma2 servers running simulateneously

We can run around 700 A.I on one server with heavy stress testiing scripting and approx 25 players connected and stay at + 20fps serverside which is above what you need to keep the A.I intelligent

BIS doesnt seem to have optimised the server engine to run more than 2 cores

which is a shame, because then we could have 1 server running with maybe a couple of thousand A.I.

If its just a player v player server you need, then this same spec from what I have heard can easily accomodate well over 60 players from a data centre located server

Hope that gives you an idea as to the spec u need

Depends on the map, island, and if many ais. on warfare be ace2 we hit around 10 fps with 32 players after 3hours but some months ago i remember when we had around 25fps for the first hour then droped to 15fps 30min later but when we played it on everon island we hit 1 to 2 fps. and thats on a i7 920 @ 3.4ghz

You could try treaking the arma.cfg network settings to get better fps

Hi all,

we have this dedi specs:

CPU Core2Duo 3.00 GHz

4 GB RAM

100MB Internet connection

all was ok, untill this weekend, when 40 players login on server and everyone were freeze and cant move. the server didnt went down, it was like is stucked. when 20 log out it was ok.

My question is: Do you think the server cant run 40 players or is more likely that we have wrong set the server.cfg

This is our server.cfg

MinBandwidth=15000000;

MaxBandwidth=100000000;

MaxMsgSend=1024;

MaxSizeGuaranteed=1024;

MaxSizeNonguaranteed=64;

MinErrorToSend=0.0025;

MaxCustomFileSize=0;

[terox 316]

My question is: Do you think the server cant run 40 players or is more likely that we have wrong set the server.cfg

Here is ours

	MinBandwidth 		= 800000;  
MaxBandwidth		= 25000000;
MaxMsgSend 		= 256;
MaxSizeGuaranteed 	= 512;
MaxSizeNonguaranteed 	= 256;
MinErrorToSend 		= 0.003;
MaxCustomFileSize	= 100000;

We did some extensive testing, tweaking for coop play to come up with these figures.

I'm not saying that these figures are perfect, but our server seems very stable.

I would disregard a lot of the information on these config variables as described on the BIS wiki, they seem to be full of erroneous assumptions.

Our server cpu is a higher spec than yours (Xeon X5570's)

We have 2gig more ram however i dont think that has any bearing on your problem

I assume you have the server located at a data centre and if so, we could probably assume that actual bandwidth and quality of bandwidth for both servers is similar.

Your config values, in comparison to ours would show a requirement for a faster system and more available bandwidth, therefore try tweaking them down a bit.

I would also assume by looking at those values that you suffer from desync

Your o/s may need some tweaking too

Hope that helps
