Hey all. We are using the grid on one of our internal pages with ~2000 records. It loads up fine on the first load, but when we reload the grid, the request will take ~1 second, but the browser will hang for another 4-5 seconds to display the data.

Is there any fix other than adding pagination to display less than the 2000 records on the same page?

You should search the origin of the problem in your code which you don't posted here. Typical error could be usage of multiple changes of the page instead of usage of cellattr, rowattr and custom formatter together with gridview:true option. You should search for origin of the performance problem presumably in your code from loadComplete or gridComplete. I recommend you to read the answer to understand what is refow. The answer and another one shows how to use cellattr, rowattr. One more answer demonstracte how to rewrite code from loadComplete or gridComplete to improve dramatically performance to the grid rendering.

Oleg

I have had this issue, the easiest way to diagnose it like Oleg said was to use the *Complete functions. I loaded up a firefox profile with FireBug and used console.log(...) to report back the status and that's how I found my issue.

Also, if you're using a dynamic data set, make sure it is running fast enough, one of my problems was that the php function wasn't flushing out the results fast enough, it was waiting until it had the full set before replying.
