& XSLT You may also explore Saxon's Performance Analysis
features. It allows you to generate tabular HTML
report of stylesheet execution time.

Following is a description of "Saxon Performance
Analysis" from its documentation.

"The output identifies instructions in the original
stylesheet by their name, line number, and the last
few characters of the URI of their module. For each
instruction it gives the number of times the
instruction was executed, the average time in
milliseconds of each execution, and the total time.
The table is sorted according to a weighting function
that attempts to put the dominant instructions at the
top."

I have tried this feature and have found it quite
useful.

I believe comparing the performance analysis reports
of different XSLT transformations using Saxon, will
help you to compare the complexity of the
stylesheets..
