[xsl] Stylesheet optimisation

My question might be a bit too general, nevertheless: Are there any general
strategies/options to optimize the rendering performance of an XSLT set for a
given project?

A bit of background to the given project:
- a portal website with about 5000-10000 pages including dynamic pages
(applications and forms) which need to be rerendered with each request
- each page is rendered in about 3-5 different steps (due to the portal
software and/or pagetype)
- most steps use the same XML, only for some steps on selected pages a
different XML is used
- each step is rendered with its own XSLset, some are mostly the same and
included, some are completely different

Would there be any general optimisation options which could be applied to the
XSLT (not the general setup)?
At the moment only caching of mostly static pages and prerendering of some
steps is done. Would something like custom XSLT extensions (for complex stuff
done now directly in XSL) be a help?

I know this *is* quite general, but any hints are very much appreciated...
