YDL Users,

On October 25th, Rutgers University conducted a test of the "SciMark 2.0a=
"=20
Java benchmark on a dual 1GHz G4 Apple PowerMac (the most recent model) a=
nd=20
has to offer the following data (larger numbers are better):

Yellow Dog Linux 2.3:
SciMark 2.0a

While individual scores varied from less than 1.12x to 3.42x, the Composi=
te=20
Score demonstrates that given the current implementations of Java for YDL=
 and=20
Mac OS X on the same physical computer, YDL is more than twice as fast.
