Can you give more information about the tests you did?  Linux uses (by 
default) a different method for emulating floating point to ADS, and I suspect 
this is the cause of your performance loss.  It's also possible that glibc is 
a little slower, but I doubt this would account for the factor of 50 or so that 
you seem to be seeing.
