Hi Andreas, indeed, in the document I only have one page-sequence over 500+ pages. There are approx. 10 tables that stretch about 1 - 150 pages each. There are also nested tables. There are 3 images (< 30kb) on each page's footer. Your idea is to rewrite the stylesheets that each table is enclosed by a separate page-sequence. Am I right?

Are there any > tweaks? I set the -Xms and -Xmx options to its maximum (1200m). How much memory FOP 1.0 uses depends heavily on the FO structure. Are you trying to render one fo:page-sequence of 500+ pages, containing a lot of nested tables? If so, then it can very well be that 1.0 is more memory-hungry than 0.20.5. If the 500+ pages are neatly distributed over page-sequences of around 20 pages, the matter becomes quite different. On the other hand, one also needs to take into account the fact that 1.0 implements more features. Extra functionality requires extra resources, obviously, so I would expect /some/ difference. FWIW: I did a similar test myself once, and a document that required +1GB heap on 0.20.5 took 'only' 640MB of heap on 1.0 (well, actually 0.94 at the time). Are there any other specifics you can give us about the document? (e.g. lots of fo:instream-foreign-objects or other images, forward references to pages towards the end of the document...) If it is possible and it contains no confidential information, you can send me the FO source off-list, and I will have a closer look to see what the options are, if any, to bring the required amount of memory down.
