I just saw that QtWebKit in Qt5 RC2 let the memory consumption increase by factor 3 (7MB to approx. 24 MB). When doing some testing with the JS bridge (sending data from JS to C++ ) the memory consumption in Qt5 even grew up to a factor of 6 or 7 (step by step to approx 45MB, and it did not go down anymore), while in Qt4 there was almost no memory increase (finally 8 or 9MB).
I used my very simple test program which  I attached at bug https://bugs.webkit.org/show_bug.cgi?id=104540

Did you also experience such a high memory consumption?
