Any chance to improve XHTML to PDF rendering speed in FlyingSaucer /OpenPDF ? I am using version 9.1.20 of flying-saucer-pdf-openpdf library. Simple XML took almost 5 seconds. Took 0.5 sec with the flying-saucer-pdf lib.
org.w3c.dom.Document doc = parseXMLContent(xhtmlContent, validate);
Date tim = new Date();
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(doc, null);
renderer.layout();
renderer.createPDF(out);
renderer.finishPDF();
log.debug("xhtml2pdf took " + ((new Date()).getTime() - tim.getTime()) / 1000.0 + " seconds");
