Subject: DOCBOOK-APPS: Chunking performance

I've been experimenting with improving the performance of the chunking
stylesheets. The primary goal of my experiments was to get rid of the
hairy (and probably expensive) recalculation of prev/next for each

If you're curious, please give




a try. Try using chunk.xsl with chunk.fast=0 and chunk.fast=1, the
output should be the same, but the "fast" version should be faster.
Using fast chunking requires support for the exsl:node-set() function
(which Saxon and xsltproc provide). Without it, there won't be any

The chunkfast.xsl stylesheet may be marginally faster than even the
fast version of chunk.xsl. It avoids calling exsl:node-set()
repeatedly, but will crash and burn if that function isn't supported.

                                        Be seeing you,
