---------------------------------
Summary: 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.
