Zitat von David Carlisle <davidc@xxxxxxxxx>:

  I think it's only natural, that processors perform better with well
  written stylesheets than with stylesheets, containing only one very
  big template.

That doesn't sound natural to me at all. Splitting things up by named templates is like using functions and subroutines in other languages. It's easier for a human to understand and maintain but if push comes to shove you might exepect to get some minimal performance gains by inlining the functions (templates) back into your main template so avoiding the function call overheads.

Ok, it's not natural :) But I think authors of xslt processors will focus primarily on real world stylesheets than on weird ones. So the processors (if the authors succeed) will more likely to perform good on well written stylesheets. :)

Are you sure that somewhere in your big template you don't have <xsl:apply-templates select="."/> That would cause stack overflow...

Yes, I'm sure. I only select child-nodes. And the stylesheet works, when there are not 500 but only 200 block-level elements.
