I use personally a modified version of RDS' fast_lower() (URL might wrap):
http://www.listfilter.com/cgi-bin/esearch.exu?fromMonth=9&fromYear=9&toMonth=9&toYear=9&postedBy=Juergen+Luethje&keywords=lower

Applied to the whole text in Euphoria/Doc/Library.doc, it runs in 50% of
the time that lower() uses.
