Description

We're seeing a performance regression of up to 20% or so between 10.6 and 11.2 for XSLT compilation.

Compiling the docbook-fo stylesheets, from the command line with -nogo, we're seeing an increase from 2206ms to 2645ms. A breakdown of this cost, obtained by setting the static variable Compilation.TIMING to true, is attached.
