First, I would check that you are using recent DocBook XSL stylesheet
distribution (1.78.1).

Then you can run Saxon with -t switch which will show you how long
resources are loaded and transformed. This can give you some insight.

Multi-core processor will not help, unless you are using features from
commercial version Saxon-EE (and those features are not used in DocBook
stylesheets), transformation runs in a single thread.
