Hi Mike, > I don't know what XSLT profiler you are referring to. The Saxon profiling I was using the Stylus Studio profiler - http://www.stylusstudio.com/xslt_profiler.html > tool only tells you how much time is spent in each template, which is not > very useful here as everything is in one template. Generally, finer > resolution than this is not necessarily helpful because XSLT processors do a > lot of lazy evaluation, which means costs are not always incurred at the > point where the costly expression is written. > Nothing elaborate, I just set -Xrunhprof:cpu=samples on the command line and > looked at the resulting java.prof.txt file, which immediately revealed (to > someone who knows the Saxon internals, at any rate) that at least 90% of the > time is spent evaluating xsl:number. > Many thanks, again. - Sujata
