| | 18 | 1st Day |
| | 19 | * Anti talking about tile based rendering. Working prototype using QImage exists, need to get support from Qt to draw to QPixmap from a thread, Discussion if tiling should be supported for everyone or just mobile/QGraphicsView |
| | 20 | * BenjaminP talking about plans for Qt4.7 to regularily run benchmarks, automate and store results during the development. |
| | 21 | * Talking about OOM handling, checking each allocation vs. just getting killed by the OS vs. getting signals from the OS and then stop loading... |
| | 22 | * Zoltan talks about a valgrind skin to instrument memory usage including showing how much and who was allocating the memory, common call frames can be removed from the trace. |
| | 23 | |
| | 24 | 2nd Day |
| | 25 | * Holger talks about the QtWebKitPerformanceWork and QtWebKitPerformanceUtilities and how the can be used to measure Qt performance. Comments included limiting the bandwidth used for the fake http server. |
| | 26 | * Shortly discussed the RGB16 approach to save some memory by using color converting RGB32 images to RGB16, specially on symbian a 16bit backingstore exists and painting can be done in 16 bit. |
| | 27 | * Shortly discussed using WebCore/platform/image-decoders. The downsampling is a feature one would like to use, also the performance appears to be better. We should explore using them. |
