Which one's faster

Hy there.
I would lie to know which version is faster for the transformer:

Example 1:

<xsl:template match="/">
        <xsl:for-each select="SITE" />
                <p><a href="@url"></a></p>
        </xsl_for-each>
</xsl:template>


Example 2:

<xsl:template match="/">
        <xsl:for-each select="SITE" />
                <p>
                <a>
                        <xsl:attribute name="href">
                        <xsl:value-of select="@url" />
                        </xsl:attribute>
                </a>
                </p>
        </xsl_for-each>
</xsl:template>

In resume, what's faster: creating the text directly or using the
<xsl:attribute> for generating the text?
