We are having issues trying to multi-thread iText due to memory issues. When we parse through normal size files, our single and multi-threaded programs work fine. Once the file sizes get bigger (1.5Gb in some cases) even the single-threaded program can run out of memory. With a 500Mb file anything more than 2 threads causes OOM. We can get rid of the OOM condition by not using the getRandomAccessFileOrArray, but then it runs so much slower it negates the whole reason for using multiple threads.
Our current plan is to try and breaks the file up into smaller 'chunks' and then multi=thread the processing of the chunks. That is what I am in the process of doing right now. I'll let ya know how that works when I get it finished and tested. Edward W.

I don't believe that making significant modifications to iText is the way we'd like to go about solving this problem. I was hoping to hear from someone that has used iText in a multi-thread / multi-processor environment, and if iText performed better for them than it has for us in our simple test. We would also appreciate some input from the iText developers. Thanks in advance to all. rm. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php
