What background activity could be running that would steal CPU cycles
while my application is running?

I have an application that must process information every 100 msec and
sometimes the process does not complete on time. It is very random.

Is there some windows XPe application/service that could be delaying
my application?
 
That depends on what is in the image.

1. Does the same thing happen under Windows XP Pro?
2. Do you have Task manager installed? If so, is there a process that is
taking up more memory cycles?
3. Have you considered a real time extension to XPe to get better
deteriminstic behaviour? www.tenasys.com

Click to expand...

Network, USB, harddisk, it could be anything :/ Windows is not a real
time OS by default...
