speed optimization

Hi

I'm looking for a free, simple, and easy, way to find bottlenecks.
I'd like to be told stuff like
  "Saxon spent 70% of his time in line 5 columns 7-20 of foo.xslt."
or
  "In the template starting on line 7 of file foo.xslt there are two
  unused varables, two redundant document() calls, and 10 lines of
  potentially dead code."

Do you know a good profiler?

Is this one useful?
  http://www.xslprofiler.org/
Does it work well with Saxon 6.5.2 and 7.3.1?

TIA,
Tobi
