Incidentally, one minor comment
Only xsltproc provides a command-line switch for running the transformation
time multiple times
Saxon has had such a switch for some time, though only recent releases have
documented it (-repeat:99).
I had subsequently found the original three switches in the Saxon source
code and had mentioned them in later deliveries of the tutorial.
I think there's another important (if obvious) point that's not made in the
paper: don't assume that your performance problem is in the XSLT code until
you've drilled down to that level. I did a bit of tuning for a client
recently where it turned out 80% of the cost was spent in some simple
user-written code to generate the XML input for the transformation.
To paraphrase Knuth (another giant who must surely have sore shoulders
by now): premature optimisation is the root of all evil.
