4:10 AM - CPU usage on Windows XP with video

I did an experiment while streaming video on netflix.  I set iexplore to use processor affinity + above normal priority.  The result was a 10% cpu usage drop at first, and periods at 10%.  Prior to that it was constant 60%. 

It's interesting the performance difference.  I wonder if it's cpu cache or changes in the scheduling.
