[Bug 1325001] Re: improve app startup time

 

This bug was fixed in the package webbrowser-app - 0.23+14.10.20140826
~rtm-0ubuntu1

---------------
webbrowser-app (0.23+14.10.20140826~rtm-0ubuntu1) 14.09; urgency=low

  [ Olivier Tilloy ]
  * trunk → rtm-14.09 sync: - Instantiate webviews on demand, only when
    they really need to be shown. - Show placeholder artwork and text in
    empty tab previews. - Reduce startup time of both apps by means of a
    few tricks, all related to asynchronous loading: * ensure loaders on
    the critical path load their components asynchronously * instantiate
    the error sheets asynchronously, as they are not needed right away *
    use Component.incubateObject(…) instead of Component.createObject(…)
    to instantiate objects asynchronously where possible * instantiate
    the history and bookmarks models asynchronously (LP: #1325001)
