Hi, I actually have no experience of processing large files like this. However, what is obvious is that memory is the key for this kind of operation. I am guessing now, but I would suggest you need at least 4-8 times as much memory as the size of your file, especially if using FOP to do page numbering and things like this. So, forget about processing time for now and just start with a box that has somewhere in the order of 1GB of RAM. AND MAKE SURE THAT YOU CONFIGURE YOUR JAVA ENVIRONMENT TO USE A LOT OF IT. If you do not do this, Java will only use 64Mb regardless of how much physical memory you have. Look up the -Xmx parameter for your Java runtime. Also, you might need to fiddle with the stack size (-Xss) if your document is complex. I would suggest starting with -Xmx800m which will allocate 800Mb of RAM to the Java process. I would also suggest the Linux is likely to be more efficient than Windows (at least it's likely to offer better memory management and have a smaller footprint). Once you can make it work completely, then you can start thinking about scaling up the processing to complete the task in a reasonable timeframe. I am not sure if any XSL or FOP processors are multi-threaded, so I don't know if going multi-processor is going to help you. Hope that gets you started, Dan. -- Danny Yates -----Original Message----- From: Rakesh [mailto:rakesh@xxxxxxxxxxxxxxxxx] Sent: 27 February 2003 05:05 To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: RE: [xsl] OMR Mark for folding machine Hi Dan, It should process 150MB of XML data in a reasonable time say max 10 minutes. Actually I have to process 20GB of total Bill Cycle which is broken down for small-small XML data for Corporate accounts. These XML file becomes of 100MB and some 120MB for few corporate accounts which can not be broken down further. FOP stops processing at my end just after 10MB which has really become the serious matter of concern. I have changed the SAXON parser as SAXON7.3 and JDK 1.4. I tested it with XALAN 2.4. Please Please advice me for the system h/w requirement to achieve the target. Also should i go for Windows 2000 or Linux OS? Hope i have described the problem. Regards! Rakesh D.

I would suggest that an 8-way 3.06GHz P4 Xeon machine with around 1TB of RAM would probably provide "optimal" performance.

I have no idea what is OMR, but the only way to get page number (not during XSLT stage, but during formatting) is fo:page-number or fo:page-number-citation formatting objects. -- Oleg Tkachenko Multiconn Technologies, Israel XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list *************************************************************************** This communication (including any attachments) contains confidential information.
