[XSLT] [Q] Recursion Question/Concern

I am new to the list, so please forgive me if I am
asking something answered elsewhere.  I have searched
the archive and FAQ and have not found the answer I am
seeking.

I need to count and number "records" in an XML file. 
It would seem that recursion is the answer, but I am
concerned about performance.

When using recursion I have noticed a 10:1 performance
decrease over not using recursion.  I assume that user
error is responsible.

If I do not use a recursive function then my template
will process in roughly 1 second.  I do not get the
desired results because I need individual numbered
lines.  When I use the recursive function then
performance goes to roughly 10 seconds.

Any and all help would be appreciated.  Thanks in
advance for your time.


Example of XML file format:

<DATA>
  <RECORD>
    <INFO1>xyz</INFO1>
  </RECORD>
  <RECORD>
    <INFO1>abc</INFO1>
  </RECORD>
...
</DATA>

The desired result would be:
1 xyz
2 abc
...


In my XSL document I do the following:
<xsl:template match="/">
  <xsl:call-template name="NumberStuff">
     <xsl:with-param name="Counter" select="1"/>
  </xsl:call-template>
</xsl:template>


<xsl:template name="NumberStuff">
  <xsl:param name="Counter" />

  <xsl:if test="count(//RECORD) + 1 > $Counter">

    <xsl:value-of select="$Counter"/>
    <xsl:text>|</xsl:text>
    <xsl:value-of select"//INFO1">

    <xsl:call-template name="NumberStuff">
      <xsl:with-param name="Counter" select="$Counter
+ 1" />
    </xsl:call-template>
  
  </xsl:if>    		
</xsl:template>
