Am I using V8 engine?

[DerekDomino]

Hello,

I've run the following javascript benchmark in an Qt 5 application running a WebView and observe significant differences (factor 2.4) with Chromium (Google Chrome 26.0.1410.65):
http://octane-benchmark.googlecode.com/svn/latest/index.html

For the Qt 5 application, I've created a new project from Qt Creator by using the "Qt Quick 2 Application" wizard and replaced the main.qml by:

@
import QtQuick 2.0
import QtWebKit 3.0

Rectangle {

width: 1024
height: 768

WebView{
url: "http://octane-benchmark.googlecode.com/svn/latest/index.html"
anchors.fill: parent
}
}
@

The Qt 5.0.0 64 bits application was compiled on Mac OS X 10.7.5 in Release mode with llvm 4.2 on Intel 2.2 GHz i7.

The scores are the following:

• Qt 5 app: 5461 (Qt 5.0.0), Debug mode scores around 4800
• Safari: 8630 (Version 6.0.3 - 7536.28.10)
• Google Chrome: 13208 (Version 26.0.1410.65)

The following test report 'JSC' for Qt 5 app (may be this test is not that rock solid):

Is it possible to have V8 running with a WebView?

V8 support was abandoned.

But you can try to break the rules: https://github.com/qtwebkit-v8ers/qtwebkit-v8

Looks like I don't but I heard it on IRC and mailing lists. Afair, maintainer of Qt WebKit claimed it.
