Speed up Vista boot by using two cores

[Guest Carlos]

This article

http://www.techwarelabs.com/articles/editorials/dirtyvista/index_2.shtml

Step Three, items #1, 2, and 3

states that Vista normally uses only one core during boot, even if you have

a dual or quad core processor, and that by enabling the additional cores you

can get a boot time reduction.

I will quote the important part:

 

"Click on Start then type "MSCONFIG" hit enter then click continue through

the UAC we talked about earlier. This opens a small screen containing some

interesting startup options, playing with this will allow you to start and

stop most things that run in the background. The startup tab tells you which

company each service belongs to so you can use this to try and slim up your

startup. One of the biggest impacts you can perform to your cold boot is in

unlocking the potential of your new machine.

Select the boot tab, then choose advanced options...

 

Check off Number of processors, and set that drop down box to the highest

available number.

 

What this is doing is unlocking Windows Vistas ability to use multiple cores

to start up. When Vista was designed in order to make it compatible with

older hardware this option was set to (1) so that it will always use only one

core. By unlocking it you allow Vista to boot using all of your cores this

can lead to a boot time performance increase of 15-40% for a cold boot and

about 10% for a warm boot or a return from standby"

 

Has anyone confirmed this or has evidence that it can be true?

haven't tried it, but the test to verify is pretty easy. Give it a try and

see if it actually speeds up your boot.

Re: Speed up Vista boot by using two cores

 

Did not work for me and my Q6600, on a warm boot test.

To be precise, time between pressing the button and the welcome screen (user

selection) was reduced by 1.05secs...

Re: Speed up Vista boot by using two cores

 

I think that is bunk, what the element tells Vista is:

 

"The maximum number of processors that can be utilized by the system;

all other processors are ignored."

 

If one thinks about it for more than 10 seconds the "tweak" seems to be

a myth, the tweak is built around increasing the number of available

processors, yet the element suggested is not used to increase the number

of processors, it is used to limit the number of available processors.

This element is the same as the /NUMPROC= switch used in the boot.ini on

previous NT versions:

 

/NUMPROC=

 

Specifies the number of CPUs that can be used on a multiprocessor

system. Example: /NUMPROC=2 on a four-way system will prevent Windows

from using two of the four processors.

It would probably make more sense if they would suggest changing the

UseBootProcessorOnly or ForceMaximumProcessors element instead of the

NumberOfProcessors element, and I am not saying that using these other

elements would make any difference in the boot time, I don't know if

using these other elements would make any difference.

John,

Thanks for your feedback.

Your comprehensive explanation has been quite interesting.
