I agree, these are all things that might give you 1% improvement. The only
other thing I can suggest is looking at the format-number() calls. I've
known that be really slow on some implementations. Try taking it out and
seeing if it makes any difference.
I would like to propose to move the formating to the css as much as
possible (that means all what is implemented by the browsers you want
to support - this is a lot but OT on this list). Begin your
measurements with the stylesheet below and observe carefully any
changes when you add "string-formating". I use SAXON 6.5.5 with the -t
switch to get the timings. I've changed a few things, if you have
questions don't hesitate to ask.
