Re: [xsl] XSL-FO to PDF conversion speed

Thanks so far. The present solution has 12 tables. I could probably do without some of them and merge the rest into just 6 tables. That might give me a small reduction in time. Now, my clients problem is bigger than my 5s for a single transformation. They run a batch of 700-800 transformations (still very few compared to the millions of runs others face as a challenge). Am I right that even for just 700-800 XSLT/FO transformations, there is a lot to gain from using FOP in a servlet, or would you advise me to go for a commercial FO processor right away? And what about the XSLT part. At the moment XALAN is used. My tests for a single transformation show that not much is gained from using an XSLT 2.0 processor (Saxon) and optimize the stylesheet for 2.0. I can hardly measure the difference. Is this still true for a batch of 700-800 transformations? Even split seconds gained ad up, but could there be other speed benefits from using an XSLT 2.0 Saxon processor compared to good old XALAN when we are talking about a batch job?
