By "twin", I assume you mean dual? Dual Xeon? If only one CPU is doing all
the work, then the program you're using is not SMT enabled. In your case
with dual Xeons, you should have four "Performance" graphs (for CPU usage)
in task manager and in a non-multithreaded environment, only one of those
graphs will show significant activity.
On the plus side, the "free" CPU will allow you to multitask without much of
a performance hit.

I have a twin 3GHz PC with hyperthreading. I use sonicencoders to burn
video
dvds of digital TV recordings and it takes a long time (2.5-4 hours to
burn a
2 hour movie). I think virtually all the resource needed is processor
resource.
When it is transcoding the file, if I look in task manager, one of the
processors shows as being highly used (80-100%) - but generally the other
is
idle, unless I'm doing something else.
Is this the behaviour I should expect (hyperthreading is a mystery to me)?
I
would have hoped that it would use all the processing power it has
available
to it - is there any way I can exploit the fact that I have two
processors?
Cheers
Eric
