Description David Simonek 2002-10-16 10:42:54 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 15:57:23 UTC

Optimization tool analysis showed following bottlenecks:

1) JavaDocFSNode - JavaDocFSSettings - is complete initialization
needed and why it takes so long?
15.71% - 806 ms -
org.netbeans.modules.javadoc.search.JavaDocFSNode$2.getValue()

2) Why should be whole BeanInfo loaded just to get icon? 
19.57% - 1004 ms -
org.netbeans.modules.javadoc.search.JavaDocFSNode.getIcon()

3) DocSourceManager.initComponents does too much things in
initComponents (although majority of time is class load time)
35.92% - 1842 ms -
org.netbeans.modules.javadoc.DocSourcesManager.initComponents()

4) Init of TableTreeView itself is slow
 10.51% - 539 ms - org.openide.explorer.view.TreeTableView.<init>()

Javadoc maintainer, please evaluate 1), 2) and 3) soon. Thanx.

Comment 2 Petr Nejedly 2003-07-09 15:11:39 UTC

BTW: This snippet from JavaDocFSNode is Really Cool(tm):
public Object getValue () {
  if( getJavaDocFSSettings().getSecondRoot() != null )
    return getJavaDocFSSettings().getSecondRoot();
  else
    return null;      //NOI18N
}

Comment 3 _ pkuzel 2003-09-09 17:13:22 UTC

I'm now responsible for JavaDoc module.

Comment 4 _ pkuzel 2003-09-11 20:59:17 UTC

Javadoc Manager will be replaced by JavaDoc resources. (libraries)
