Thats right, the xslt will only take a small percentage of processing time compared with the XSL-FO formatting process. Calling FOP from command line each time means there is the overhead of starting the Java JVM for each ticket. The way around this is to write a Java program which can receive requests via some mechanism, e.g. JMS Queues, watching disk files, database tables, etc etc. And then change your perl program to send a request using your choosen communication method. The details of linking Java to Perl are well off topic for this discussion group, but you should find once completed that the average ticket generation time is reduced by a good margin.

Re: Enhancing FOP command line speed
Maybe someone has written a small JAVA daemon yet? I would prefer this solution from my PHP scripts. You can call FOP from PHP: ? $pdf = output.pdf; $fo = input.fo; $options = array($fo,$pdf); $java = new Java(org.apache.fop.apps.CommandLine, $options); $java-run(); ? You have a good tutorial here: http://xmlvortrag.bitflux.ch/ The support for Java is expected to be improved in PHP 5.1. But caution because FOP wastes too many memory. Building the PHP manual takes about 1 GB of memory :) Nuno - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

So no speed enhancement to direct command line and not as stable as system call. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Enhancing FOP command line speed
I would go to the PHP site/ML's/FAQ's, etc., and look at how to keep a Java application active in memory for your PHP calls. Once you find out how that can be done, I would then move away from a FOP command line to an FOP-embedded program (see http://xml.apache.org/fop/embedding.html for examples) that you can keep active for your multiple documents.
