Qt WebKit API is slow, true?

[useryy]

Using this code to load a webpage

iWebFrame->load(QUrl("http://www.ifanr.com/64307"));
    qDebug()<<QTime::currentTime().toString();
    connect(iWebFrame, SIGNAL(loadFinished(bool)), SLOT(process_LoadFinished(bool)));

iWebFrame->load(QUrl("http://www.ifanr.com/64307"));
    qDebug()<<QTime::currentTime().toString();
    connect(iWebFrame, SIGNAL(loadFinished(bool)), SLOT(process_LoadFinished(bool)));

To copy to clipboard, switch view to plain text mode 

It takes 5+ minutes to get response in the slot function.

Even if I set the url to a local html, it still takes 3 minutes.

Not sure it's my reason or not.

Loading "www.google.com" takes 21 seconds - This proves that the enviroment is correct.
Another page is from engadget.com, which takes 16 minutes. The page and its log is also attached.

It depends on the site and its servers.

Your example on my box returns:

MainWindow::entrance() 
Get main frame 
Connect 
Begin loading 
End loading. Time: "09:33:35" 
baseUrl is:  "about:blank" 
MainWindow::process_LoadFinished(). Time: "09:33:36" 
Ok 
baseUrl is:  "http://www.google.co.uk/"

MainWindow::entrance() 
Get main frame 
Connect 
Begin loading 
End loading. Time: "09:33:35" 
baseUrl is:  "about:blank" 
MainWindow::process_LoadFinished(). Time: "09:33:36" 
Ok 
baseUrl is:  "http://www.google.co.uk/"

google takes blow a second to load, the ifanr link takes a bit longer but still not as long as in your case.
