While profiling actions on web.xml and other desriptors I see XML parsing using validation, namespaces and schemas. One posility is to consider schema caching - http://www-128.ibm.com/developerworks/xml/library/x-perfap3.html Probably not a win for the first use but can be usefull for next reparsing. And the reason why I saw XML parsing is XmlMultiViewDataSynchronizer that builds model when I select web.xml node (and navigator is loading the content of documented and concurrent synchronizer is parsing). Why do we need synchronized when there is no modification? I think we do not need to init the synchronizer before doing a change or at least before opening in editor, do we? Erno? Changing issue type to TASK since the problem should be fixed in the infrastucture (see the issue 80723). latest results Netbeans 6.5[080921]
