Running the following transform against that file using Kernow's
performance testing facility:

<xsl:stylesheet version="2.0"
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	xmlns:xs="http://www.w3.org/2001/XMLSchema"
	xmlns:t="http://www.example.com/test"
	exclude-result-prefixes="xs t">

<xsl:param name="age" select="25" as="xs:integer"/>
<xsl:param name="gender" select="'female'" as="xs:string"/>

<xsl:template match="/">
	<xsl:for-each select="/t:people/person[@gender eq
$gender][xs:integer(@age) lt $age]">
		<xsl:value-of select="concat(string-join((@first, @last, @age), ',
'), '&#xa;')"/>
	</xsl:for-each>	
</xsl:template>


</xsl:stylesheet>


Gives this result:

Ran 5 times
Run 1: 445 ms
Run 2: 178 ms
Run 3: 216 ms
Run 4: 335 ms
Run 5: 163 ms
Ignoring first 2 times
Total Time (last 3 runs): 714 ms
Average Time (last 3 runs): 238 ms


That time includes writing the result to the output window.
