Re: Performance Question
Sorry, I should have included these details also: Our PDFs are produced during a batch process, meaning the JVM is started once and all PDFs are then created. This, of course, means the JVM stays "warm" and we can take full advantage of HotSpot compilation. We also have implemented a style sheet cache, so once the style sheet has been used once the compiled version is reused over and over, which definitely helps performance. All of our XML/XSLT interfaces use JAXP, meaning we can plug in different XML/XSLT processors. We currently use Saxon 6.5.2 because it's the fastest, but it appears the recently-released Xalan 2.5 has closed the gap considerably. Even though the computer has 1 GB RAM available, we only allocate a max heap size of 512 MB.

I use Saxon 6.5.2 as the XML parser and XSLT engine. It also uses custom XMLReaders to produce SAX events which are processed by FOP. We usually see a PDF production rate of 8-9 pages per second, and we sometimes produce PDFs that are 1500+ pages. The only real problem with FOP is some of the XSL style sheet tricks necessary to insert intermittent page-sequences so FOP doesn't run out of memory. Hope this helps. "Christian Neuroth" To: <[EMAIL PROTECTED]> <[EMAIL PROTECTED]>cc: Subject: Performance Question 04/30/2003 03:30 AM Please respond to fop-user In my company, we are currently using StreamServe to produce documents (basically invoices). 50.000 docs/day, 3.000 prints, 47.000 pdf. The final document averages 3 pages (there are some exceptions with up to 1000 pages - very rare, however), a document containing only one graphic (logo). I am puzzling whether I can shift from StreamServer to FOP. Are there any people out there who apply FOP to achieve a similar volume?

The final document averages 3 pages (there are some exceptions with up to 1000 pages - very rare, however), a document containing only one graphic (logo). A good rule of thumb is two pages per second on moderate hardware (Intel P4 1GHz), if the JVM is kept warm. If the documents share the graphic, FOP's image cache is an advantage. This might fit, barely (1d=86.4ksec ~ 172 kpage ~ 50k documents). If you are batch processing, you can try to balance it over several machines. Run some benchmarks and make up your own mind.

RE: Performance Question
I tried to process lesser amounts of docs (muuch lesser volumes!) and got into serious trouble. I have abbandoned FOP, but I must admit that there was Cocoon inbetween.
