Subject: [xsl] XSLT 1 vs. 2 stylesheet performance issues From: "Ilya Sterin" <sterini@xxxxxxxxx> Date: Wed, 30 Jul 2008 12:37:38 -0400 |
I'm a bit stumped by the performance issues we're having. We have an xslt 1 compliant stylesheet that takes 10 minutes to run in xslt 1 processors (Saxon, Xalan, libxslt) and a few seconds in Saxon 9B. I'm not sure what it can possibly be. We don't use anything out of the ordinary, we extensively use for-each, choose, and if. But again, I'm not sure why it would take so much longer using an xslt 1 processor. We need to utilize xslt 1 processor for various reasons if possible. The processor seems to take most of the time in starting the transformation. Using oxygen, the debugger says Starting transformation and stays there for about 10 minutes before transforming in a matter of seconds. The same is true with using any of these processors in command line mode. Is there some performance documents available anywhere that outline how xslt 1 gets compiled and it's efficiencies/inefficiencies, how things are indexed, etc....? I searched the web with no luck. Thanks. Ilya Sterin
