I think something is badly wrong here.  That's less than 1/2 the speed
of my Athlon 4850e (2.5GHz) and only 60% more than my Atom N270.  None
of the other figures you posted look anomolous.  Are you sure the CPU
is actually running at full speed and you haven't done something like
disable the caches in BIOS?
