slow grids loading in 2.1.0

[xin]

We discovered that the 2.1.0 version is so much slower than 2.0.4 when large data set is used or multiple grids in used in a page.  For example, we have a page consist of 4 grids in a local HTML page, version 2.0.4 only takes 2 seconds to do the initial load and rendering, but version 2.1.0 takes 22 seconds to do the same task.

So my question is:
a). are you aware of performance issue in the new version?
b). do you have any plan to fix this performance issue?

Thanks.

You need to use virtualX: true and virtualY: true when working with large data sets in version 2.1.0

I tried VirtualX and VirtualY.  It works and achieves similar performance as that of old version 2.0.4.
Many thanks.
