Dserver hardware?

[EAF_Starfire]

Although I am new at this dedicated server/mission busines and are running the Dserver from an old dual 3GHz (E8400, (GB RAM) I have been looking into some of those new CPUs with a lots of cores and less GHz.

 

This question might be directed at the developers as it is highly technical.

 

 

How well does the Dserver scale with the number of CPU cores?

Will I benefit from more cores with less speed?

 

Does Dserver benefit from Threading?

 

 

How does the Dserver dependt on the speed (GHz)?

 

 

Does the Dserver benefit from 64bit computing?

 

 

Are there any performance difference between Intel and AMD, and how much %?

 

 

How much does the CPU L2, L3 matter?

My understanding is that the DServer runs on a single core, so multi-threading is not an issue and processor speed is far more important. Ideally you will want a processor speed of 3.5GHz plus.

 

As for your other questions, I don't really know the answers except to say that I would always prefer a 64-bit processor and that I personally prefer Intel to AMD though I admit that this is largely a legacy of my age and past comparisons between the two brands.

How well does the Dserver scale with the number of CPU cores?

Not very well. The most CPU utilization I've seen was a notch over 100% of a single core. I guess it uses one thread for mission logic, AI and physics, and another thread for net I/O, the first thread being the bottleneck. I'm running two instances with lots of AIs on an i3 running at 3.5Ghz, and that's been fine for me.

More GHz = more AIs and more players

 

Does the Dserver benefit from 64bit computing?

It requires 64-bit. It shares code with the client, which is 64-bit only.

Although this does not suprise, I am disapointed in this legacy approach.

There are and have always been a limit to the GHz and with the cost of electric power the multi-threading/multi-kernel is a lot more efficiant and cheap (according to the CPU makers).

The other problem is the lack of scale-ability.

We had the same problem during the SEOW campaigns in "IL-2 1946", a game which was from 2001

 

 

I do hope that the developers prioritise this in the future.

I believe it's on their todo list but after kuban

As Coconut said the Dserver is very single threaded so benefits from a fast cpu.

I am running it on a Core i7 6700K running at stock speeds (4.2GHz boost) which is pretty much the ideal situation, I am considering putting the overclock back onto the cpu as it can maintain 4.6GHz stable on stock voltage which would give me just that little bit more oomph

 

Does Dserver benefit from Threading?

Not at this stage.

 

How does the Dserver dependt on the speed (GHz)?

It depends pretty hard on IPC so a high clock speed and low thread/core count with great IPC (instructions per clock) cpu will do the job nicely.

 

Does the Dserver benefit from 64bit computing?

As Coconut says its a 64bit process, however I rarely see ram usage go much over 1gb, so you won't need a bucket load of ram in the system.

 

Are there any performance difference between Intel and AMD, and how much %?

Yes there is, but it depends on which AMD and Intel CPU's you are talking about. The AMD FX series is garbage as it is a very old architechture that wasn't very efficient or high performance even when it was first released, it has aged very poorly as well. The intel cpu's have not made any huge leaps in performance over the years, however they are much faster than the older AMD FX range in every way, even the older 2nd and 3rd gen core i3/5/7 cpu's eat the AMD FX series for breakfast.

AMD Ryzen should in theory be about on par with the current gen Intel cpu's or maybe 5-10% slower in single threaded performance, however I have not tested my Ryzen system with Dserver as the 6700k is better suited to the task.

 

How much does the CPU L2, L3 matter?

I am unsure, I havent done enough testing to give you any firm results.
