My co-worker did a very small test saying XOM 1.0 did take about 10% more time to load/build/etc the document he tested it with. Of course this is not a real performance test but thats what he went with.
I too doubt dom4j will be much faster but they are accustomed to it and there should be not disadvantages by changing (advantages I see in XOMs focus on correctnes. Simplicity for me is a big advantage too but I myself did not use dom4j before).

But I was wondering if XOM 1.1 will be a lot faster in some areas after the discussions about performance optimizations on this list. Being only a moderate I was not following everything in detail but had the impression 1.1 should be much more optimized, is that true? When is 1.1 expected as a final version?

thanks
Christof

Would be interesting. I'm not aware of such a thorough study. Having said that, I'd be somewhat surprised if they were more efficient. It probably also depends on the main usage pattern.

hello,
are there any performance comparisons between lets say XOM and
dom4j/JDOM etc?

I try to persuade some colleges at work to use XOM instead of dom4j
(which has bitten some projects with some nasty details mostly issues
about whitespace handling) but they question the performance of XOM.

Googling did not bring any real help, so I'd think I'll ask here...

thanks a lot
christof
