Speaking of which, I just grabbed NB6 and set up Standard 1.0.6 and Standard
1.1.2 projects to get a better idea of the performance difference. Using the
Test.xml attached a few years back and the following loop:

<% long start = System.currentTimeMillis(); %>
<x:forEach select="$doc//countries/country">
country id: <x:out select="id"/>
country description: <x:out select="description"/>
country countrycode: <x:out select="countrycode"/>
country carcode: <x:out select="carcode"/>
country nationality: <x:out select="nationality"/>
</x:forEach>
<% long delta = System.currentTimeMillis() - start; out.println("Duration: " +
delta + "ms"); %>

Here's what I got:
Standard 1.0.6: ~150ms
Standard 1.1.2: ~16000ms

I'm running JDK 1.5.0_12, Xalan 2.7.0, Xerces 2.7.1, Tomcat 5.5.23, and WinXP SP2.
