XALAN Version 2_3_1 performance

[Varadharajan K V <va...@mindtree.com>]

Hi,

We were using XALAN Ver 2.0 in our application. After doing the performance
testing we have collected the following statistics for XSLT Transformation


XALAN_J Version 2.0
Length of XML(in bytes)	416813	416813	417230	426794	436165	
Transformation in (milli Secs)	23436	22957	22719	56746	91644	

Then we changed the Xalan version to 2.3.1 and we noted the following time
measurement for the 

XALAN_J Version 2_3_1
Length of XML(in bytes)	416805	416805	417220	426783	436163	
Transformation in (milli Secs)	5618	6081	5927	11530	12949	


We could find see a marked improvement in transformation time taken. Is this
marked difference is because of improvement incorporated in the new version?
Is there any official document confirming the performance improvement? Or
anybody else have experienced such marked performance improvement by using
this version.

If this version is more stable then we can go ahead in changing the version
in our production environment.

All above metrics are for a particular screen in the application and hence
the xml structure and the xsl used for transformation is same but only the
xml size is varied hence the length of XML is changing.
