Description David Simonek 2002-10-15 16:15:07 UTC 
First open takes longer then 1 second, which
violates UI responsiveness rules.
I will cooperate and help with speedup. I'll try
to identify time-consuming places using optimizing
tools, ask you for further information, perhaps I
will attach some patches. See measured numbers here:

Comment 1 David Simonek 2002-10-22 17:59:39 UTC 
Optimization tool showed following bottlenecks:

1) Parsing of java source before wizard open
62.24% - 10529 ms -
org.netbeans.modules.java.parser.ParsingSupport$Processor.run()

2) Wizard content initialization, done before wizrad is shown on the
screen (most of the time takes TableTreeView) 
 4.9% - 829 ms -
org.netbeans.modules.java.imptool.FqnPanel.initAllComponents()

3) First paint of tree table is slow
13.16% - 2227 ms -
org.openide.explorer.view.TableSheetCell.getTableCellRendererComponent()
4.31% - 730 ms -
org.netbeans.modules.java.imptool.IdentifierNode$PackageProp.getPropertyEditor()

4) some Wizard.Panel impls extends JComponent, which is wrong

Comment 3 Tomas Pavek 2003-02-03 16:36:48 UTC 
Should here the technique from issue 30604 be used?
Comment 4 Tomas Hurka 2003-02-12 10:28:45 UTC 
Done in trunk. It was implemented using asynchronous post-init (issue #30604) of first IMT wizard panel.
