That's exactly the same problem I ran up against. Hence my investigations into properties and memory consumption. On my current setup (as per the last patch under 41044) and using my current 16MB fo file, the object counts are as follows: 349576 instances of class org.apache.fop.fo.properties.CondLengthProperty 145647 instances of class org.apache.fop.fo.properties.KeepProperty 126237 instances of class org.xml.sax.helpers.LocatorImpl 116521 instances of class org.apache.fop.fo.properties.SpaceProperty 87814 instances of class java.lang.Object[] 87458 instances of class java.util.ArrayList 87394 instances of class org.apache.fop.fo.properties.CommonBorderPaddingBackground 87394 instances of class org.apache.fop.fo.properties.CommonBorderPaddingBackground$BorderInfo[] 87394 instances of class org.apache.fop.fo.properties.CondLengthProperty[] 81632 instances of class char[] 48548 instances of class org.apache.fop.fo.properties.LengthRangeProperty 42649 instances of class java.lang.String 38841 instances of class org.apache.fop.fo.properties.CommonMarginBlock 38839 instances of class org.apache.fop.datatypes.LengthBase 38839 instances of class org.apache.fop.fo.properties.PercentLength 38838 instances of class org.apache.fop.fo.flow.Block 38836 instances of class org.apache.fop.fo.flow.TableCell 9710 instances of class org.apache.fop.fo.flow.TableRow 5021 instances of class java.lang.Integer 4329 instances of class java.util.HashMap$Entry 1521 instances of class java.lang.Class 787 instances of class java.awt.Color 667 instances of class java.util.HashMap$Entry[] 658 instances of class java.util.HashMap 330 instances of class java.util.Hashtable$Entry 201 instances of class java.util.WeakHashMap$Entry 181 instances of class org.apache.fop.fo.properties.EnumProperty 160 instances of class java.util.concurrent.ConcurrentHashMap$HashEntry[] 160 instances of class java.util.concurrent.ConcurrentHashMap$Segment 160 instances of class java.util.concurrent.locks.ReentrantLock$NonfairSync 127 instances of class java.lang.String[] 116 instances of class java.util.LinkedHashMap$Entry 110 instances of class byte[] ... As you can see, there's still a lot of value in getting the compound properties reusable - which I still intend on doing. This won't make it possible to handle arbitary documents, but will at least raise the bar somewhat. I'm also currently reading through Knuth's Digital Typography. Can anyone point out any sections I should pay particular attention to w.r.t. FOP's usage, Regards, Richard
