I don't think the 64bit vs 32bit or *nix vs win makes a difference since the app is running in a 32bit Java VM. At least I would assume no difference. I think what really uses RAM is large continuous page sequences and big image files. Using smaller page sequences will result in better memory performance because (as I understand) FOP builds the page sequence in RAM before committing it to disk. Therefore, crafting XSL with more smaller page sequences uses less RAM overall.
But my gut feeling is that approx 2GB of RAM alloted for the Java Virtual Machine should be more than enough for 12,000 pages barring images.
