When running FOP without turning off the debug information written to the standard out, text such as this is printed when FOP finishes rendering a PDF page:
Parsing of document complete, stopping renderer Initial heap size: 111343Kb Current heap size: 107377Kb Total memory used: -3966Kb Memory use is indicative; no GC was performed These figures should not be used comparatively Total time used: 5562ms Pages rendererd: 10 Avg render time: 556ms/page Most of the info, like total time, average time, etc is self-explanatory. But could somebody please explain the meanings of the heap and memory size lines? I'm working with creating large (600 page) PDF reports. Sometimes they work, and give some sort of info regarding heap size and memory, and sometimes they don't. When they do work, it always says that no GC was performed, which puzzles me considering how large the document is (I'm not using any forward references and I am using liberal amounts of page-sequences). But if the report gets much bigger it crashes, I'm guessing because it runs out of memory. I'm just trying to get a little more insight into how things work. Thanks! -Ryan
