We have a program that needs to be heavily optimized (processing a tenth of the expected volume). The program is heavily using SAX-parsing ! I was wandering if any body had place were I could start optimizing (getting the cheap bucks first).

Any idea is welcome,

\T,

p.s. :
I need the cheap bucks in Jackarta SAX not in optimization !

Thomas,


Jakarta Sax doesn't exist...
If you mean SAX, it's an independent project http://sax.sourceforge.net.
It is by no means slow though!!

If you mean the parser is slow... well... maybe there can be something done there... (try Saxon's AElfred for example, I had a factor of two compared to Xerces).

But generally the other side of the road is slow: allocating memory as the result of parsing...
That's the case when you build a dom/jdom/dom4j representation...That's the case when you transform also (they have an internal representation).


Not too sure of anything else...

Paul
