Re: [xsl] Performance Problem Question: Web Container (Tomcat) vs. Console excecution

[George Cristian Bina <george@xxxxxxx>]

Hi Andreas,

There may be two possible problems:
- you are not using Saxon but the Xalan that comes with Java 1.4+.
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.

Best Regards,
George
