Ext4 Grid Performance?
Ext4 Grid Performance?
I've seen the PPT showing the performance improvements achieved in the layout engine however I'd like to know what kind of performance we can expect on the Ext4 GridPanel.

Would be helpful to talk with Tobi as he raised grid performance immense, i guess he knows a lot of tricks and no-gos'svg Steffen

It's going to be much much better.
It's going to be a single table. So no stacks of divs containing tables which need every cell programatically sizing. It's going to make a big difference.Search the forum: http://www.google.com/coop/cse?cx=01...%3Az7of1ufqccu
Read the docs too: http://extjs.com/deploy/dev/docs/

Will it still support buffered views?

i am thinking to buy sencha so I have used Sencha paging grid for testing how it works, in this i seen one thing we need to give all the data before the grid display in the form of array, so if the amount of data will increase say 50,000 or more then also it will work well and give the same speed in sorting and other operations?
Is there any other way so we don't have to bring all the records at one time and give in array format?
Please replay me

There are a number of different approaches to large result sets, discussed in many threads. Try searching for the LiveGrid extension and also 'grid performance'. Performance improvements brought by Ext4 are not going to solve all the issues related to displaying massive amounts of data.

@alindsay55661: that's at least 2 MB of data. Are you pulling that all down to the client for display? Seems excessive. I have grids with 10K+ rows and 20+ columns, but the pagination, filtering and sorting is all done server-side. The standard ext grid works fine for that.
