I have an application that fetches data from the table and displays it in a grid. Since the data im fetching is too large(about 2 lakh records) it is taking approx. 2 minutes to load the grid. Is there any way to reduce this time delay?

Don't tell me you are getting all the records from the backend to front end (200,000) in a single fetch. If that's the case I am completely spell bound.

I don't know any user reading 2000 screens.
One screen, maybe 2, 3 for the most relentless users.
You should investigate how to return more appropriate data, just the really needed ones.

Hey, 2.17 Billion rows downloaded to my web cache in 0.07 sec. Must be magic. Shocked

Unless of course Google is NOT sending me all the results..... Hmmm.

It just gives an estimation (and not a real number) and try to directly go to page 100 and you're out.

There were discussions on this on AskTom getting rows N through M of a result set (search for google all along this one).
