Hello madhusudan,

The column and grid resizing performance depends not only on the count of the columns but also from:

- Your browser
- Browser plugins if any
- Browser console/debugger is active
- Additional CSS on the page
- Custom styling for the columns
- Your machine
- Number of rows
- Any custom JavaScript or third party scripts in your page

I would recommend you to go thru the list and check out what is causing the biggest issues. For example try out in new page, try out different browser see what happens with less records, and etc.

Hi Vasil,

Thanks for the quick response.My observation is as below-

Yes it depends on the browser as when I tested it on Chrome,it was quite faster compare to IE but 

When i removed all additional CSS and custom CSS applied for the grid as well ,i can't see any improvement on IE browser.

Please help me on that issue.

Hello Madhusudan,

Do you use the latest version of the suite and IE 9 or newer? We know for some performance issues in IE8 but they can't be fixed.

If you send us sample project, I could profile it, to see what is causing the bad performance and provide you further assistance on resolving it.
