Poor performance of AW with multiple grids on the page


Problem :
There are around 50 AW Grids on my page , each with around 100 columns and 1 row.
These grids included on the parent page on click of a twistee image.
As I go beyond 15 Grids expansion/rendered on my page , the Performance of the browser reduces majorly.
Expanding any more twistees for Grid starts taking lot of time and the browser sometimes hangs.
The memory/CPU usage spikes up to aroung 75-80% on the machine.
Any other operation on the browser shows similar results.

I've noticed in my development that having too many objects in the DOM will cause browser performance issues. I suspect this may be the cause of your performance issues.

I too have seen this issue.
I was looking to an onclick drop down menu as a sultion for a context menu and the performance just went to the floor, so I am now stuck with trying come up with another way to delete line.

(I work with Smriti.)

The main question is:

Is there any way to get reasonable performance from a page that has 50 grid widgets on it? Or must we re-design the UI so that the grids can't appear together?

Other questions:

Is it possible to create, say, just one big grid widget and reveal only pieces of it in the 50 places?

Does the slowness come from # of objects, the # of listeners, the # rows + columns, the # of copies of DLLs, a fault in IE...?

Thanks for any guidance.
