Some process is interrupting my process and causing process delays.
The delay is in the 50 msec to 100 msec range. What XPe processes
might be causing this?
 
Bill,

There are thousands discussions about XP/XPe real-time performance on the Web.
For instance, read through this thread:
http://groups.google.com/group/micr...d/browse_thread/thread/d314816090ef10ea?hl=en

By nature XP kernel is not real-time OS kernel. XP scheduler doesn't promise your processes or thread will get their time slice in
time they need it or for the time period they need it. The situation is slightly better on Vista where lots of work has been done on
kernel and separate services to make sure Multimedia applications (and not only) can run glitch-free. But it is still far away from
real-time OSes like WindowsCE or LinuxEmb or etc.

Without much work you can do on the system at least make sure your process threads are running in high (time critical) priority.
Make use of tools like Performance Monitor to analyze what's going on in your system on micro level.
