Multiprocessor Initialization Delay at Desktop?
In comparing two XP Pro installations, one built for a uniprocessor machine
and the other for a dual-core version of the same machine, I am experiencing an annoying 40-60 second delay in the loading of a touchscreen driver after the appearance of the XP Desktop on the dual-core unit, compared to a 5-10 second delay on the uniprocessor unit. In fact, both images are being tested on the same machine, so the only difference should be the multiprocessor support present in the second image. Does XP require additional time to initialize multiprocessor support after the appearance of the Desktop before completing the loading of other peripheral drivers? Is there anything that can be done to minimize the additional delay? |

The BIOS settings get changed with every processor installation,have you
monitored the settings at every change.

Multiprocessor Initialization Delay at Desktop?
Andrew:
Thanks for the quick reply! In fact, I am not swapping the CPU between sessions with the two images. The single-core image built on a uniprocessor machine is being run on the same dual-core unit interchangeably with the dual-core version. The hardware remains the same; only the software changes, and it is the dual-core image running on the dual-core hardware that is taking longer to initialize. That's what I'm trying to understand. There seems to be some "overhead" associated with setting up the session environment for multiple cores. I'm hoping someone can either confirm this, or point out some other configuration options I need to adjust to eliminate the additional delay.

Your problem is that a dual-core CPU is not the same as having more than one
processor. The delay is probably coming from the multi-processor OS looking for another CPU and not finding one. The uniprocessor image is the one you should be using for your set-up.

"The BIOS settings get changed with every processor installation..."
is utterly false, and another example of Andrew giving advice he knows nothing about. --- Leonard Grey Errare humanum est Andrew E. wrote: The BIOS settings get changed with every processor installation,have you monitored the settings at every change.

Actually, he is correct to a certain extent this time. If you swap out a
2GHz CPU with a 2.6GHz one, some of the BIOS settings will change accordingly- the multiplier, frequency (if different), etc. SC Tom "Leonard Grey" wrote in message ...
