We experienced a very similar problem, though we're not using GXT. Doing a navigation in IE was taking a crazy amount of time, whereas in other browsers the navigation was fine.
We wound up doing the navigations by getting the user "gesture" (click, or whatever) indicating that they want to navigate. When this happens, we do the work as if our history listener got an event In addition, we manually track the history token. Then, in a DeferredCommand, we do the History.newItem() call to update the history stack. Of course, this means that we have to handle the case that when our history listener gets a notification, but we're already at that history token. It's not fun (and possibly bug-prone), but at least our customers aren't cursing us... jay On Mar 13, 10:02 am, maku <[email protected]> wrote: > Hi, > > we have a very strange performance problem especially in context with > history handling and IE6 / IE7 > > Our application is based on GXT and is already a rather large one (1.6 > MB). > > On less powerfull computers (e.g. Netbooks -> Asus EEE 1000h) the > performance of history handling is really bad (calling > History.newItem) > > E.g. time performing History.newItem(...) lasts ca. 4.5 seconds > > It seems that it depends on the size of the application. > > When I try the same with a reduced app (size 980 KB) the performance > is dramatically better (but of course not satisfying) -> Time to > perform History.newItem(..) reduced from 4.5 seconds to 1.6 seconds. > > Is it possible that the reason for this is IE's IFrame handling? > > Does anybody of you know the reason for these kind of problems.
