parasbuy Posted February 4, 2011 Report Share Posted February 4, 2011 Hi Folks,I have a 3.33GHz 6-core Intel Xeon Mac Pro with 16GB of RAM, but running Windows 7 64-bit. Despite having a pretty good level of hardware installed, I am getting the hourglass often. From the CPU Meters, I can see that the first core is maxing out, and the other five are barely registering. There is plenty of headroom in the RAM, only 2GB of 16GB are being used. The Disk I/O and network connections are also not over-utilized.This hanging happens often, and eventually clears out without the system crashing. I was just scrolling a PDF and the same thing happened. Any ideas? Shouldn't the system be able to distribute the performance over 6-cores automatically so that one core does not get over-taxed?Thanks.

Boris Posted February 4, 2011 Report Share Posted February 4, 2011 It would be nice to know how you did your Windows install ( as per Maneman's question - last post in your other topic) :- http://forums.windowsforum.org/index.php?showtopic=47554&view=findpost&p=320491 Quote Link to comment Share on other sites More sharing options...
parasbuy Posted February 5, 2011 Author Report Share Posted February 5, 2011 OK... I just don't think it's relevant; but perhaps I'm wrong here...- i have a Mac Pro with four drive bays- installed Mac OS 10.6.6 on the primary 1TB drive- installed Boot Camp- installed Windows-7 64-bit on a 500GB drive via instructions from Boot CampNow, when I load up, I hold down the option key and as the computer gets through the BIOS sequence, a very basic menu comes up to select booting Mac OS or Win7. I select Windows-7 and I'm into Windows.I'm not running Windows through the Mac OS, via VM-Ware or Parallels, etc... just going directly into windows.I also see the same problem with the Cores when I am in Mac OS.Thanks.

parasbuy Posted February 9, 2011 Author Report Share Posted February 9, 2011 An update on this... - added the Windows drive into the privacy pane of Spotlight so that it will not try to index the windows drive any longer- there is plenty of headroom in the RAM, only 2GB of 16GB are being used- plenty of bandwidth on the network connections - disk activity is pretty clear, not hung-up on anything... i'm also not running any virtualization that i know of... no VM Ware, Parallels, etc. Brought my virtual memory down to 50KB, as well.Still getting the hourglass, though...- I've also noticed that when i get the hourglass, that it is not just the first core that maxes out, but sometimes it's the 4th core, or the 3rd core, or the 6th.... seems like this might be the primary issue for why I'm seeing delays at times, so here's some more info in case it helps....- the top CPU% process is changing as you would normally expect it to... sometimes it's Firefox, Thunderbird, Lightroom, etc., depending on the app being run; it's usually running at <4% normally, occasionally going up to 10% if all cores are taken together, meaning one core may be maxed out but including the other 5 that are very lightly loaded, the CPU level is ~4% to 10%- by Threads... Firefox is 38 to 42 threads running the Daily Show, Thunderbird is 35, Lightroom 26, Songbird 21, Excel 15 at the moment as I'm unsuccessfully trying to load it up... So, I'm not sure, but I think the question is... why are the applications processing not being loaded across multiple cores? shouldn't the OS being doing this automatically? is there any re-configs or installation I need to do to have Windows distribute this loading better?thx.
