DOMNamedNodeMapImpl::item() 10x preformance improvement
-------------------------------------------------------
Key: XERCESC-1452
URL: http://issues.apache.org/jira/browse/XERCESC-1452
Project: Xerces-C++
Type: Improvement
Components: DOM
Versions: 2.6.0
Environment: All environments
Reporter: Jeff Keasler
10 second bug fix -- change MAP_SIZE constant in DOMNamedNodeMapImpl.hpp from
193 to 17.
I use literally millions of DomNodes each having 2-10 attributes and
DOMNamedNodeMapImpl::item() is horribly implemented. It makes sense to fix the
problem by changing the definition of MAP_SIZE to 17. Even people with 50
attributes will get decent performance if you make this change, wheras the vast
majority of people who only use 5-10 will see up to a 10x performance
improvement.
Thank you.
