Entity Framework and performance

[archimede]

I'm using telerik components, objectdatasource and Entity Framework 4 in my web application.
The grid is very simple and the columns have some Telerik comboboxes.

The problem is that the loading of the grid is very slow: it can take 4-5 seconds. A normal Entity Data Access is 2-3 seconds. What can I do to optimize performance?

Hi Archimede,

We have many optimization techniques and I am sure some of them will be of great help for your project . The info below summarize the most important performance info we already have in our documentation resources:
Optimization Tips series in the blogs:

Optimizing the RadGrid performance.
Please review the following links on how to optimize the performance of RadGrid:

In the worst case when a grid is bound to huge data in the web server the RadGrid gives great performance. Working with web services and JSON increase the performance:

 ViewState size:  Some of the grid operations can work with completely turned off ViewState.
    Example: http://demos.telerik.com/aspnet-ajax/grid/examples/programming/viewstate/defaultcs.aspx
    In client-side data-binding scenarios you do not need the ViewState also:
    Example: http://demos.telerik.com/aspnet-ajax/grid/examples/client/databinding/defaultcs.aspx

 JavaScript $create clause size: Depends on selected features. Can be turned off along with all other resources:
    Example: http://blogs.telerik.com/VladimirEnchev/Posts/08-07-15/Telerik_RadGrid_Section_508_Compliance.aspx?ReturnURL=%2fBlogs.aspx

 Number of requests: Most of the grid images come from the grid CSS sprite which minimizes number of requests to the server for resources. Can be minimized with RadScriptManager and RadStyleSheetManager.

I hope his helps.
