I was suggesting the heuristic "if you've got a 64Mb machine > don't try to process more than about 6Mb of source data." I just wanted to point out that this is a really common source of problems for people, and the heuristic depends on the scenario. For example, if you have a 500MB of RAM, and are transforming only a 1MB (on disk) file inside a servlet, you are still going to be in big trouble once you get a certain number of simultaneous connections against the web server. The main thing that people need to understand is that resource consumption for the typical in-memory XML cache is much greater than the size on disk of the XML. That's where most people get into trouble -- they prototype with small XML and few connections, and things work fine. But they never realize that their memory bloat is a factor of 5x or 10x until the run out of memory. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
