View Full Version : Load tesing on Sencha Grid

21 Mar 2013, 10:18 PM

We have tried putting 3000 records on sencha datagrid (Ext.grid.Panel) using local store. The grid is performing quite badly , the grid controls are dying.

Any idea if Sencha Grid can support high number of records ?

You would never load that many records into a grid in one go. This is a scenario where you would use paging, or a buffered / infinity scrolling grid.

Well , I have tried out paging also even then the performance was bad. I haven't tried buffered scroll yet.
Hope that helps.

How many results per page were you showing, and how many columns did each row have?

I use many grids inside single page apps, running 50 rows per page, and sometimes ~15 columns per row, and never experience any performance issues (except perhaps in old versions of IE).

I am using 12 records per page with 14 columns. Also, I am using IE8 as the browser .
