I was cleaning up cereal a bit and I contemplated replacing db2* (using openjade and DSSSL) with xmlto (using passivetex and XSLT). HTML generation went down from 6 s to 4 s, PDF generation up from 30 s to about 5 min.
Needless to say I'm staying with the DSSSL styles. At least I got a chance to fix some errors caught by the stricter XML parser used by xmlto.
