Hey, reading is not such a black art, you know.  I specifically said 4Suite in 
current CVS.

We got 4XSLT to the point when it was about as fast as Saxon and Xalan before, 
back in the 0.10.x series, but subsequent features and changes added up 
significant performance hits, cuminating in the 0.11.1 release.  We went back 
to optimizing for the next release, and have restored it to its prior 

The CVS version of 4Suite is even easier to install than 0.11.1, so you must 
just not want to follow my challenge...
