At the very best, you could avoid running out of memory by increasing the heap size. The effect on the processing time is marginal at best. It just causes the garbage collector to run less frequently, which may shave off half a second if you're lucky. If you want to avoid JVM warmup, which probably represents about 80% of the mentioned 10 seconds (if not more), then by far the easiest solution is to familiarize yourself with the servlet concept. There is an example servlet that is distributed with FOP, in package org.apache.fop.servlet. Deploy this in an Apache Tomcat container, and start up Tomcat. If all goes well, you can then send simple HTTP requests to the port that Tomcat is running on to convert your XML to PDF. Note that, since the servlet comes as a part of FOP, such a solution requires no real Java programming. I would estimate at most half a day of work to get yourself basically started, even if your Java knowledge is minimal. Do mind the disclaimer on the FOP website (link below) concerning the lack of security in that basic servlet. Deploying it into a production environment as-is is definitely not recommended, so if that is the goal, then eventually you will need to dive into the Java code, and enhance it to meet the more rigorous requirements for production servers. If you just need to run it on your own system, for your personal use, there is no need to modify the servlet. Obviously, any enhancement that improves this servlet and does not require external libraries whose license is not compatible with the Apache license, will be warmly welcomed as a donation. ;-) I think you'll be surprised at how much of those 10 seconds can be avoided, with relatively little effort. More info can be found at: http://xmlgraphics.apache.org/fop/trunk/servlets.html The source code for the servlet can be viewed at: http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/src/java/org/apache/fop/servlet/FopServlet.java?revision=732631&view=markup Apache Tomcat can be downloaded here: http://tomcat.apache.org/download-60.cgi Hope this helps!
