Here I am :)
I said "may" because it should not sound as a general recommendation to
use the Hyperthreading mode of your processor. In many cases
Hyperthreading (virtually 2 CPUs while being physically 1 single CPU
core) can improve the operation speed. If running several applications
in parallel you can have the feeling that applications react more
smoothly. On the other hand I remember reports where active
Hyperthreading reduced the CPU operation speed over all. So it depends
on what you are doing in specific with your system.
