Do you have any way to deal this issue directly with ExtJS folks, other than Sencha forum?
This is a critical and urgent problem for us, as this makes us impossible to release our new product version.
Thanks.
I've spent a lot time this last week investigating the problem and the end result is not much to show.
I all my tests (Win7), the memory grows with each new page (iframe) that is opened. The memory growth is relatively consistent in each browser (Chrome, Firefox, IE9) growing to approx 300mb after 20 tabs are opened. When the tabs are closed, the memory is slowly recycled with each of the browsers performing this in a different way.
With Firefox, the memory does not immediately recycle upon tab close, but it does start cleaning up after a minute. The final amount is destroyed once the Page is refreshed/reloaded.
With IE, the memory it appears approx 80% of the original tab memory is recycled immediately. After closing all tabs, and waiting a few moments, the memory seems to level off at the Original Value + 20%. Obviously that value could also grow over time as the application is used.
These results are on my machine, and others testers are getting varied results, which is making this tough to test.
At the moment, unfortunately we do not have a comprehensive fix for this <iframe> memory consumption issue. We are continuing to work on the problem, but other than that I don't have much to offer. It's a very difficult problem to solve, but it remains our #1 priority.
