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)));
@

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.

The fact that you use qDebug for your timings, suggests that you are trying to profile using a Debug build. That is a bad idea. It doesn't tell you anything about real-world performance.

However, your load times are extremely slow. 3 minutes is for a local HTML page is rediculous. Obviously, Qt Webkit normally isn't that slow. That is just plain unworkable. AFAIK, it is used in Qt Creator & Assistent as well to show the help pages, and I for one have no complaints about performance there.

Thanks for the debug suggestion.

I load a local html is fast if the html is like

<html>
<body>
<h1>My First Heading</h1>

<p>My first paragraph.</p>
</body>
</html>

Except the complexity of HTML file, no other clue is found.

My Qt debug build opens google in under one second...
