Hi Stefan, My application consumes a lot of memory because it allocates a very large number of widgets. The critical structure is some sort of table where each element is a very complex widget with several labels and subpanels. My table has 100 of such widgets. Each one of them may be further expanded by the user to display 10 more subwidgets inside it, and each one of these subwidgets in turn is also a very complex widget with several labels and subpanels! In order to optimize memory consumption, I create these subwidgets on demand as the user expands one of the parent widgets.
The application runs well under firefox: it opens up with 38 MB and rises to 110 MB when I load my table with 100 widgets. From this point, each subwidget expansion takes up an average of 7 MB. I can not run such application under IE: it opens up with 59 MB, climbs to 524 MB right away after displaying the table with 100 widgets and each further subwidget expansion eats up 50 MB! In this experiment I think that no deallocations should be taking place, as I am just creating a bunch of widgets. The results show that the memory consumption of my application in IE is a factor of 7 compared to Firefox. Based on your experience would you blame IE guilty for that or could it be some issue with qooxdoo?
