How do I increase CPU performance in Windows Vista?

This blog provides you with a tip to unlock the processing power on your Windows Vista laptop.

I have been exploring my CPU processing power on my Windows Vista laptop and came across something that might be of value to you. By default, Microsoft chooses a power option of Balanced. What I noticed is that this might be a great feature if your main goal is greener computing, but I need all the CPU computing power I can get when I work on my laptop. This Balanced setting seems to throttle my CPU processor.

In order to unlock your computer's full CPU performance, perform the following:

In the system tray, click on the icon and change your power plan to High Performance, as shown in Figure A.

 

Figure A. Choosing the correct power option will increase performance.

I have developed a MS Visual C++ program with a small amount of graphics but lots of integer 32-bit processing. The program runs 4-5 times faster after changing from balanced to high performance, thus solved my overall performance problem, thanks!

These virus sit in the BIOS of every digital device.They stop the virus scanning of the memory address allocations.They limit size,speed and voltages.They were constructed at exactly the same time the BIOS file was written,probably even in the same room.I suspect that the military was in that room too.

Does he really know what he is talking about??

Actually I think that's a pretty old feature, first I saw it was in my Win2KPro Thinkpad for retarding the CPU clock speed (though it may have been a plugin and not part of the OS I don't remember now). I use a custom plan, that way I can run at full speed and just alter the close lid and sleep settings to my preference without sacrificing performance. I did notice that it is 'balanced' by default though and should be switched to 'high performance' whereas in Win2K it was the other way around. I also found that increasing the page file size in Vista helps a great deal (especially as most Vista boxes have a lot of RAM that goes unused thus creating more disk reads and slowing the machine. A good tool I found, after trying many 'instant optimizers' is Tune Up Utilities 2008. Helps reduce the bloated GUI and rreally helped make quick adjustments that actually did make a noticable difference. http://www.tune-up.com/products/tuneup-utilities/

Changing this setting doesn't unlock anything. If you look into the details of the Balanced power plan you'll see that when plugged in, everything runs at it's maximum speed. When on battery power the default setting limits the clock speed of the CPU to extend battery life. It's not about "being green" or "increasing CPU performance." It's about mobile computing.

Balthor, I think you've probably posted this to the wrong thread... That, or I'm missing something here...

It must havebeen the placebo effect. It only lasts for a short time. Does anyone read the book to get the full knowledge of their systems.

I know exactly what you are talking about and thought the same thing myself until I really looked into the different power options. Balanced did not provide me the complete use of my Intel Duo processor. High Performance did!

... I don't believe you. I don't know everything, obviously, but I've NEVER seen ANYTHING that would support what you're saying. I wonder if you might humor me and run a CPU benchmark with your laptop plugged in and power plan set to balanced, then run the same benchmark with your laptop still plugged in and power plan set to high performance?

It absolutely does. However, the default maximum processor state for the Balanced power setting is 100% just like it is for High Performance.

Windows Vista does set an maximum percentage of processor's power to be used in each power scheme... For your own reputation, please search for something before commenting it, it will save some time and you will feel better. Thank you.
