Hi, while developing our web application, I noticed some discrepancies between the behavior of the hosted mode and the Internet Explorer 7 on Windows Vista Ultimate (using GWT 1.7.1).
In general, the hosted mode is slower than the web mode; ok. So be it. _But_ there is at least one scenario that I do not understand, maybe you can shed some light on this: I have a large tree structure, which consists of a root node and 4000 children of this root. I query the children on the server side and return the children as an array of serializable XTreeNode-Objects (nothing too fancy, a name, an ArrayList of children, and a refrence to the parent XTreeNode). In hosted mode, serializing these elements on the server and de- serializing them on the client takes ~2 minutes. In Web Mode (be it in FF or IE), it takes virtually no time at all. Why is that? Incidentally, the exact opposite happens for a reason that I don't understand yet (and thus can't describe it): When checking for a list of selected elements in the tree (programmatically on the client side), it works fast in hosted mode, while it kills the browser in web mode, taking ages to complete. [I'm just mentioning this to tell you, that I'm really curious about the principal differences between Web Mode and Hosted Mode -- I am well aware that this vague description doesn't suffice as a problem description; I am yet on it ;)] Thanks for any insights (or pointers to articles/books)!
