My server is a P4 3.0GHz C, I have HT enabled, and the OS is w2k3 standard edition. I run three instances of srcds.exe on it, with two of those assigned to CPU 0 and the third plus any other processes I need to run (like psychostats log parsing) assigned to CPU 1 (I use firedaemon to run each as a service and can assign CPU affinity that way). I have had *zero* problems running all three srcds servers full on that box. In fact, I don't think I'd be able to have three full 24 player servers on that box without the OS seeing dual cpu's, logical processors or not.
Naturally, two separate, physical CPU's would be ideal (or a dual-core CPU, looking forward to those) but a P4 with HT enabled is not something that should be dismissed. - K2 http://www.hardfought.org -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joachim Sedell Sent: Tuesday, November 09, 2004 2:08 PM To: [EMAIL PROTECTED] Subject: RE: [hlds] Hyper Threading & HLDS/SRCDS Guys, if you have NT4 or Win2k disable HT, it produces cache misses and hence has a negative performance impact. For Win2k3 I think you can just leave it turned on. When having a processor with HT you do not have 1 physical and 1 logical processor as far as Win2k3 concerns. Win2k3 sees two logical processors. Win2k3 assumes them to be 2 physical processors and uses them as such. I assume that HLDS/SRCDS just runs one thread at a time. Still, let us say that the OS wants to run a thread at the same time? Then we can have two parralell threads running at one given timeslice (* not really since this is HT and not MP, but close enough) I'd recommend HT on Joachim Sedell Rapid Response Engineer EMEA GTSC Microsoft Product Support Services -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bobby Sent: den 8 november 2004 16:27 To: [EMAIL PROTECTED] Subject: RE: [hlds] Hyper Threading & HLDS/SRCDS We have numerous HyperThreaded boxes out there and we DISABLE HT!!! Seems that the bigger servers over 24 player slots run better with it off. -Bobby _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds
