Hello Dear Lucene coders!
Some of you may remember, I'm using lucene for a product (and many other internal utilities). I'm also using another open source library called Javolution (www.javolution.org <http://www.javolution.org/> ) which does many things, one of them being to offer excellent replacements for ArrayList/Map/... and a super good memory management extension to the java language. As I'm [trying to] follow the conversations on this list, I see that many of you are working towards optimizing lucene in term of memory footprint and speed. I just finished optimizing my code (not lucene itself, but my code written on top of it) using Javolution PoolContext and the FastList/FastMap/... classes. The resulting speedup is a 6 times faster code. Javolution make it easy to recycle objects and do some object allocation on the stack rather than on the head, which remove stress on the garbage collector. Javolution also offers 2 classes (Text and TextBuilder) to replace String/StringBuffer which are perfect for anything related to string manipulation and some C "union/struct" equivalent for java. The thing is really great. Would anyone be interested in doing Lucene a face lift and start using javolution as a core lucene dependency? I understand that right now, lucene is free of any dependencies, which is quite great, but anyone interested in doing fast/lean/stable java application should seriously consider using javolution anyway. Any thoughts? Jp
