If this refers to the model of your solaris machine (SunFire V490, meaning UltraSparc IV), then the numbers are actually not hard to believe. Those are almost a decade-old CPU (from 2003-2004), and SPARC are not speed deamons in the first place. Having them 10 times slower than a recent core i7 (which are very performant for floating points) seems "reasonable". cheers, David _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
