    v4 v5  
    1414 * Cut down on the usage of QUrl::toEncoded as it shows up in the profile of starting jobs.
    1515
     16 * QBENCHMARK results are hard to analyze and compare. We need a single and simple way to say if something is faster or slower.
     17
    1618=== QtWebKit problems ===
    17  * Image decoder changes to greatly reduce memory and load speed. See this [https://bugs.webkit.org/show_bug.cgi?id=27538 bug] for planned changes. The possible impact is quite big. The task would be to change the ImageDecoderQt to perform better and create the benchmark to compare WebCore decoders with Qt ones to assist with future optimations in QImageReader.
    18 
    1919 * Loading of http://en.wikipedia.org/wiki/Maxwell_equations is triggering bad "scheduling". The loading_standalone test has been extracted but is not able to highlight the problem. This is a Qt and QtWebKit issue, it must be understood first.
    2020
     
    2222
    2323 * The fuzz testing will make QtWebKit go in infinite loops and stop working. This situation needs to be analyzed as this can be a serve reliabality problem.
     24
     25 * Research a better QImage -> QPixmap migration strategy. Currently we convert every QImage to a QPixmap and this is bad for times where we need to draw a scaled version of the image or will only draw this image once.
