xsltc's indentity transform too slow

           Summary: xsltc's indentity transform too slow
           Product: XalanJ2
           Version: CurrentCVS
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: org.apache.xalan.xsltc
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: tom.amiro@sun.com


Xsltc is very slow in performing the identity transformation 
(i.e., newTranformer() or newTemplates() with no stylesheet argument)
from various sources to results. Currently, xsltc uses an internal 
representation of the default identity transformation stylesheet,
compiling it to translet initially, and then loading the byte 
codes n times for n transformations. A redesign of this feature 
should be able to eliminate the compilation and invocation of the class 
loader, which are very expensive with respect to performance.
