poor IE5/XSL performance?

A client of mine sees very poor performance when rendering XML documents via
IE5 and an accompanying XSLT style sheet.  An XML document renders without
perceptable delay on my Windows 98 system; he experiences a delay of a
minute or so on his Windows 2000 system.

Both XML document and style sheet are relatively short (fewer than 100 lines
each).  The style sheet conforms to the W3C XSL working draft of 12/1998
(<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">).

Any ideas?
