View Full Version : Ext JS 4.1 Performance issue

3 May 2012, 2:46 AM

I am working on small application in which I am fetching 1000 records from server through Ajax and after fetching, I am populating those 1000 records in a ext js grid. On hitting the request to server I get the response in 1 sec however,data rendering in grid takes around 7- 8 secs. Is there any perormance issue in UI components or UI side?

Which browser are you using?

With that many records, you may want to consider paging or buffered grid.

I also have the same issue. When am trying to load 2000 records into grid it is taking lot of time. To resolve this I used pagination with page size of 50.

Thanks Scott for your reply...

I am using the Mozilla Firefox vesion 11. I haven't tried the pagination or buffered grid yet.

I will try and let you know the results.
