Subject: RE: [xsl] Performance Problem Question: Web Container (Tomcat) vs. Console excecution From: "Andreas Guther" <aguther@xxxxxxxxxxxxxx> Date: Thu, 23 Jun 2005 09:54:32 -0700 |
George: You are right, I get as XSL Vendor Apache Software Foundation running in tomcat and on console I get SAXON 6.5.3 from Michael Kay. Any hints how to change to the right XSL vendor? Is this a path problem or do I have to set something specific?

You can output <xsl:value-of select="system-property('xsl:vendor')"/> from your stylesheet to see what processor is used. - the time difference is in the network transfer and not in the XSLT processing.
