I am looking at this - so far the most important problem seems to be folds (there are lots of them in the file). I have seen a near-OOME situation too. Will take a look at the hints after these two. A change in navigator - TreePathHandles are computed lazily for navigator elements, which is both performance and memory improvement: http://hg.netbeans.org/jet-main/rev/f3e78d858d9b Caching of ElementHandles, which improves memory consumption (the effect is probably visible mainly in pathological cases like Big.java from bug #194816): http://hg.netbeans.org/jet-main/rev/334ea69563f6 Integrated into 'main-golden', will be available in build *201104270000* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main/rev/f3e78d858d9b User: Jan Lahoda <jlahoda@netbeans.org> Log: #197743: compute TreePathHandles in navigator lazily to improve performance.
