Hi there, I'm making a real-time application running on XPe, and I found the
program on XPe run 18% slower than on XP Professional version. It's is a
multi-thread program, my computer has two Xeon processors. I've imported all
devices in .pmq file which was produced by tap.exe. I just wonder whether I
need to add some special components to improve the computer speed.

Thanks.

Hi Ray,

Just a thought,

Install device manager, and look if there are some troubles with chipset
drivers.

You're probably already using it, but if not, make sure
you have the "ACPI Multiprocessor PC" component in the
image and not one of the "... Uniprocessor PC" components.

HTH,

Thanks, Tony. Yeah, that component has been added, and I opened Task Manager
to monitor running, both processors work. Anyway, thanks.

Will System Pagefile import the system performance? I didn't enable it till
now. Thanks.

What kind of resources are involved in your speed test?
Video, memory, network, disk, etc?
 
If you have enough memory to execute you're program, then you don't need
page file.
Page file will not speed your computer, but it might slow it down.
 
Video is not a problem cos I installed the drive and didn't count in test.
117MB data need to be loaded from hard disk, and then test. The computer has
512MB memory, and if I run the problem the second time, those data should be
loaded from disk cache instead of disk directly, right?
I checked the XP professional just now, may I set the Performance Options?
And how? That is "Control Panel"->"System"->"Advanced"->"Settings" of
Performance->"Advanced".

Thank you so much.

Ray,

Add the "System Control Panel" component. If I were you I would add all the
control panels, and device manager until you figure out the problem, and go
from there. HTH,
