Hyper-Threading Pros & Cons Hyperthreading has been available on workstations for HP, Dell and other workstation manufacturers but was turned off in their systems shipped. Both HP and Dell, though, make the technology easy to turn on. Cons
If you are running single-threaded applications, it will reduce your performance. Problems could occur with single-threaded applications even on a multithreaded operating system. If the processor is running two threads, the chip has to split its cache--a reservoir of memory located on the processor--and other shared resources. Regular software that?s run on computers with two chips runs worse than on single-processor boxes. Most of the applications for workstations, predominately tailored for Windows 2000, don't take advantage of the technology. Pros
Users could see performance benefits of up to 30 percent on select applications Although a small number of applications might see a minor dip in performance, the vast majority of applications will benefit or, at a minimum, not be affected when running on Windows XP. Users running two applications at once will see similar performance boosts and experience far fewer hang-ups. Windows XP has been optimized for the technology and so have many applications * Hyper-Threading is quite a cool technology however steps have to be taken correctly in order to enjoy the full benefits. First you will need P4 3.06Ghz and above, 533Mhz Intel chipset board (845E/PE/GE/850E), BIOS with HT feature turned on, fresh installation of OS to enable MP kernel. From our understanding, Hyper-Threading runs best with Windows XP Home or Professional therefore turn HT on if you running applications with this OS. Windows 2000 are not optimized for HT therefore you might wish to turn it off unless you are mostly running multi-threaded applications. Users running Linux will require 2.4.18 or later but it is up to the individual vendors on how they optimize their OSes and softwares for HT.
