I stumbled on it almost by accident.
Dual AMD machines have the ability to assign memory to each CPU and have twice the memory bandwidth of a single processor machine. This ability is refered to as NUMA. See some information here http://lse.sourceforge.net/numa/faq/
Of course, not knowing that much about it, I assumed more = good, and so I gleefully turned it on, and it's been running like that for 3 months. But then I stumbled upon a website which benchmarked NUMA and discussed its support in Windows. It said that Windows Server 2003's support of NUMA is not perfect, AND it also said that applications not specifically written for NUMA support can act erratically on a NUMA machine and potentially use higher CPU than they normally would.
So last night, I ran home and gleefully turned NUMA off hoping that was the problem, and sure enough, I loaded up Chain, and Grit, and the server was able to handle it. Now both of those maps are killer, and they will always get laggy at the end no matter what CPU you run, but these maps were simply unplayable before this. Now they're back in rotation.
So enjoy!
Anyone wanna buy an FX-60 server? :compress:
Where is Grit Nights?
Glad to hear you solved the problem. Hrm...how much is that FX-60 selling for? Maybe you could save it for UT2007, but by that time there will be a fx-6000 that will smoke everything.
Would there be any benifit to still upgraiding spam vikings to the fx-60? Heck, you could slap it in your home machince and go to town too :)
