I know very little about HT but I thought that it was based in actual silicon. In other words more than one thread can run at the same time.
Am I wrong? It seams the term "Virtual CPU" would then be misleading? I don't know. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rob Harwood Sent: Thursday, June 24, 2004 5:28 PM To: [EMAIL PROTECTED] Subject: RE: [hlds] Windows 2000 or Windows 2003? No, it will share the work between the virtual CPUs, which in theory will be slightly slower than using a single CPU but most likely unnoticeable. You could however have Windows only allow it to use one of the virtual CPUs by setting the process affinity if that is your goal (via taskman). -- Rob. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Fencik Sent: 24 June 2004 20:07 To: [EMAIL PROTECTED] Subject: RE: [hlds] Windows 2000 or Windows 2003? Let me offer a better example. If you have hyperthreading on, hlds will be restricted to using half of the processor. For large servers (20+ dod playerslots w/addons), the cpu usage will max out for one logical cpu while the other remains idle. Multithreaded or not, hlds suffers from using hyperthreading.

If you have two processors then two threads can simultaneously run ... One OS and one APP thread.

Last I looked there were 5 on both my boxes. (that's with a bunch of addons loaded as well which might account for the other 2, I've never seen the thead count higher then 5 though. But simply having 5 threads that exist doesn't neceesarrly mean it's going to take advatage of MP or HT neccessarly.) -----Original Message----- From: K.

Dave, When your HLDS.exe is running, Get a process viewer and you will see more than one thread for the HLDS.exe process. Last time I looked I counted three threads when it was fully up. Anyone else know how many threads? Is my memory old? Besides, there are always OS threads (about a hundred or so) and HT would still help any box. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Fencik Sent: Tuesday, June 22, 2004 10:07 AM To: [EMAIL PROTECTED] Subject: RE: [hlds] Windows 2000 or Windows 2003?

Mike Bradley Sent: Sunday, June 20, 2004 11:35 AM To: [EMAIL PROTECTED] Subject: RE: [hlds] Windows 2000 or Windows 2003? Someone just posted an Intel link in this very thread, just a couple of days ago, which stated "Intel recommends HT be turned off in the bios for w2k machines". I am not that familiar with HT but as I understand it, it was supposed to replace multi processor (which was popular in Pentium 3). The Pentium 4 supposedly can not be easily multi processored and a departure was made from multi P to this HT technique where by a single P4 can execute multiple threads? I think this would help any app with more than one thread (which HLDS of course has several threads). -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Napier, Kevin Sent: Sunday, June 20, 2004 12:07 AM To: '[EMAIL PROTECTED]' Subject: RE: [hlds] Windows 2000 or Windows 2003? Yes service pack 4 did address as I recall one tiny issue with HT. win2k however does not take advantage of HT reguardless. I think someone mentioned that it didn't 'support' it, what they meant was it didn't take advantage of it, not that there were problems with in on win2k. Not sure really why we're talking about this as HT doesn't help hlds much if at all, infact there was some discussion last year on this list that seemed to indicate it hurt more then helped. (now if your running hlds and many other items on the box..yeah it might help you.) btw intel does not go around telling people to disable HT on win2k boxes, that's not to say however that in same rare cases it can be benificial, such as dedicated gaming server systems. -----Original Message----- From: David Fencik [mailto:[EMAIL PROTECTED] Sent: Saturday, June 19, 2004 8:36 PM To: [EMAIL PROTECTED] Subject: RE: [hlds] Windows 2000 or Windows 2003?
