Hi Ram, Please post the codes / send me the sample code files (.fo,.xsl) for us to study..
Thanks Eugene Ram Krishnamoorthi <[EMAIL PROTECTED]> 11.02.2005 20:36 Please respond to [EMAIL PROTECTED] To [EMAIL PROTECTED] cc Subject Improving FOP Performance? Hello, We are using FOP to convert to generate PDF Invoices for our Customers. We need to generate roughly around 25,000 Invoices Per Month and the Number would increase each Month. We generate PDF Docs from XML Input Files. We had Trial runs to check for Performance and Memory usage. Currently, We are just invoking FOP command directly from a Shell Script which would call the FOP Command repeatedly but making sure that not more than 2 (or sometimes 3) FOP Processes are running at any instant. I would like to have your opinion on the Performance that we observe here. The Test Machine we run FOP on has 2 CPUs and 4 GB RAM. Our Production Machine that we would be running FOP on soon has 4 CPUs though (1) In our case, An Invoice could have Several Individual Sections. The Number of Sections could vary from 10 to as high as 10,000 (depending on the data present in the XML Input). On an Average, an Invoice is around 10-20 Pages..while a small % of them exceed 500 Pages. Currently, We have a Page Sequence for each Section. We need to include only One Small Image in each Invoice. (2) There is a need to keep certain information together in the same page, so I have used Tables often..on an Average an Invoice could have around 50-60 Tables, But the Tables are not big (2 or 3 rows) and have only one or 2 columns utmost. I do understand Tables take up more memory..do they Impact Performance significantly? (3) I am using xsl:for-each in 3-4 places in the Stylesheet to loop through nodes with same Tag instead of using 'Template Match'..does that matter? At this Point, I see about 30,000 Pages being generated in an Hour if I run 2 threads. I have not embedded FOP in a Java Program Yet..Plan to do that..I have seen 1 or 2 messages mentioning that Caching a Stylesheet would help. Can someone share their experience by doing that? Are their other means to Improve Performance? Thanks for your assistance Ram __________________________________ Do you Yahoo!? Yahoo!
