QWebkit: V4 is really slow compared to V8 for large sources



  • My goal is to build a javascript framework rendered in a QWebView, not using Qml, just standard javascript.
    My library is near 1Mb of pure compact javascript with a lot of great ui components.
    I do that because my sources can be run locally (desktop mode) & remotely (cloud mode).

    On QT5.1 (with V8 engine), loading & running such library was 125ms (more than acceptable)
    Now on QT5.2 (with V4 engine), loading & running is 1480ms... same result with QT5.3

    more than 10 times slower.
    Do any body got an idea ?
    Must I use the old QT5.1 to get acceptable performances ?
