I agree but a lot of these issues have been remedied in the WinXP64 issue according to some reports.

Here is a reference to the XP-64 scheduling improvements: techreport.com "First, I tried to test the CPUs in such way as to show their benefits and limitations. To do so, I used the brand-spanking-new Windows XP x64 Edition operating system and a number of 64-bit applications. WinXP x64 is NUMA aware—that is, it comprehends the need to put data into the memory attached to the CPU modifying that data. By nature, Opteron systems require a NUMA-aware OS in order to perform at their best. Also, AMD says that the WinXP x64 scheduler is especially well tuned for dual-core processors. Obviously, 64-bit applications are the future of dual-core processors. All of the CPUs that I tested, including the moldy old Opterons, newer Xeons, and brand-new dual-core processors from AMD and Intel, are 64-bit capable. I also tried to make use of multithreaded applications where possible, although some programs aren't threaded and some types of tasks simply don't lend themselves to multithreading. The end result is that nine of our 15 test applications are multithreaded, and of those nine, five are 64-bit binaries. "
