DOM Performance

[Mahesh Paranjape <vp...@infy.com>]

Hello,
 
We want to use DOM for both constructing XML and parsing XML document.
Is there any bench marking done for Xerces for DOM.
How may KBs of data we can parse without loosing on performance.
 
regards,
Mahesh

Very complicated question that depends a significant amount on the style and
size of document that you are processing.

You should definitely take a look at "Inside MSXML Performance" at
http://msdn.microsoft.com/xml/articles/xml02212000.asp  Andy Heninger
modified
this test to test the current Xerces-C DOM implementation and a prototype
Xerces-C DOM
implementation http://www.apache.org/~andyh/  Some of the tests are not
terrible representative (for example, I think the Old Testament has 0
attributes in the document).

Dennis Sosnoski has recently published a set of benchmarks against a variety
of XML document models for the Java platform including DOM (Crimson,
Xerces), dom4j, JDOM and Electric.

There is an XMark project (primarily focused on XQuery performance) at
http://www.xml-benchmark.org

None of those are going to give you the answer that you seek, but they
should help you know the question better.
