---------------------------------------
Is it possible for you to attach 'ConvertCalendarsToPdp_1.xsl' here?
> Performance issue in XalanTransformer.transform()
> -------------------------------------------------
>
> Key: XALANC-759
> URL: https://issues.apache.org/jira/browse/XALANC-759
> Project: XalanC
> Issue Type: Bug
> Components: XalanC
> Affects Versions: 1.10
> Environment: Windows
> Reporter: Radhika MG
> Assignee: Steven J. Hathaway
> Priority: Critical
>
> We use Xalan 1.10 and Xerces 2.7 in our code built in C++ on Windows OS.
> One of our customers who upgraded from previous version of our product to the
> latest in suite is facing performance issue in Xalan transform.
> Between two versions of our product, the Xalan and Xerces have been upgraded.
> We tried to compare the time taken for transform with respective versions of
> Xalan that we used in our products, for the same xml and style sheets. The
> result is as below:
> With Xalan 1.6 and Xerces 2.3
> Xalan -t -o pdp.out Calendar.xml ConvertCalendarsToPdp_1.xsl
> Source tree parsing time: 668.791 milliseconds.
> Stylesheet compilation time: 89.449 milliseconds.
> Transformation time: 324617.921 milliseconds. (5.41 minutes)
> With Xalan 1.10 and Xerces 2.7
> Xalan -t -o pdp.out Calendar.xml ConvertCalendarsToPdp_1.xsl
> Source tree parsing time: 71.238 milliseconds.
> Stylesheet compilation time: 14.367 milliseconds.
> Transformation time: 3477100.2128 milliseconds. (57.95 minutes)
> Please suggest how we could improve the transform time. Does it require code
> change at our end?
> Please let us know.
