Hi all

I am running a GSP-company. Right now er are hosted in Germany on some quad E5405's. We are planning to open a location in Denmark in the middle of january. In Denmark, we are going to put _our own_ servers into a center.

We are planning to use the "new" E5520's (Dual quad core). They are Nehalem-based and therefore, also HT'ed. We are using TCAdmin for our systems. Now i would like to know if the panel would register all the 16 virtual cores on the server? If yes, i would like to know wherever its better to use HT or not? What would you say?

Thanks

/Chris

HT doesn't improve game server performance... Its not recommended to use for game servers. ( at least I don't use it ).

And yes, TCAdmin will register all 16 threads.

So the best thing would be to turn HT off?

I can't believe that you can actually gain anything from turning HT off... it will just prevent the OS from running multiple instructions simultaneously on the different pipelines. so you can only loose performance by switching off HT, I guess...

But it's important not to believe that HT doubles your number of CPUs even if it looks like it. So just don't run too many servers on your root...

I used to run a TF2 server on a P4 with hyper-threading. HT will give you better performance, but it is NOT an extra core. If you want more power, get a quad core.

I know it isnt an extra core, but well, i will keep it on and see how the servers performs!

Sorry, I was kinda vague on my initial post... Now you know hehe.

Just don't expect to be able to put 64 slots on each virtual core.

I am not expecting that. As far as i know, theres only 4 physical cores, the 4 extra virtual cores is just allowing the CPU to do more threads

But well, im looking forward to see what this "16-core" beast can do!
