I'm slightly surprised the improvement is only ten-fold.

Have you tried a solution using SAXON's assignment statement? If not, I'd
like to try it, if you could send me your data files. Part of my thinking
when I provided saxon:assign was that if I didn't, people were going to
invent mutable variables by using external functions with side-effects,
which seems a much dirtier solution.
