For all who travel,
I was wondering how fast those Intel mobile CPUs are. I am travelling a lot 
and sometimes I am doing some calculations to keep my Notebook busy.
Here are the results compared to an about 3 years old desktop computer.
As expected, the P-M consumes less power, but is slower and even slower  than 
expected from the clock speed ratio (2.8/2 = 1.4). Results are below.
(Did someone make tests with AMD processors (mobile, X2) ?)

Dear, Enrico or Michael, did you use the standard or any smp Kernel when you 
observed that HT slows down the 640 ? (in \var\log\boot.msg you will find the 
actual kernel number)

Ciao
Gerhard
