Task Manager CPU Usage History

[Guest]

Hi,
I'm running Task Manager to see how various programs on my computer utilize
my processor while compressing video. Some use the full 100%, some use
barely 50% and take much slower. It's helped me weed out which programs work
best for me.

Anywho, I noticed that on my home computer where I'm trying this that there
are two graphs for CPU Usage History. At work, there is only one graph for
CPU Usage. Both computers have Intel Pentium 4 processors, but my one at
home has Hyper Threading technology. Neither computer has dual processors.

So if I don't have dual processors, what is that second graph all about???

Perhaps you have one graph for each core?
HYPERTHREADING:
A technology developed by Intel that enables multithreaded software
applications to execute threads in parallel on a single multi-core processor
instead of processing threads in a linear fashion. Older systems took
advantage of dual-processing threading in software by splitting instructions
into multiple streams so that more than one processor could act upon them at
once.

Awesome, Thanks for the advice!

Actually its a Multi-Thread Execution Pipeline that Windows sees as
independant processors. Windows Identifies Multiple CPU's based on it Thread
Execution potential. Soon Intel will be releasing processors that are
multi-core and HyperThreaded. You will need Windows XP Pro to utilize all
four Thread Execution Pipelines since Home Edition only supports 2. It will
be interesting to see how this technology will integrate with x64 edition of
Windows XP Pro.

Cheers!-
