I don't want to get into a which is faster debate but this is really suspect. 
I benchmark processors as part of my job and under no circumstances have I 
found this to be true. I have found many of the Java processor are quicker 
than libxslt, including jd.xslt, Resin, Saxon and XT. Because of differences 
between JVM implementations the margin is different between Windows/Linux. In 
fact in a league table of  Windows processors libxslt comes in 6th out 
of 11.

Sablotron is always the slowest in any benchmark because of lack of support 
for compiled stylesheets. 

Hopefully in the near future I can point you at some real figures, but I don't 
have anything I can release today to back this up.
