Just a thought: are its caches sizes being correctly detected in
dl-machine.h?
A suggestion WRT cache levels shared among cores: even though it may be
tempting to use up all of the shared cache, it may cool it down for other
threads and bring overall system performance down. So it may be preferable
to sacrifice some raw performance and only use a core's share of it in order
to be a good neighbor. ;-)
