It is typically 5 to 10 times quicker (don’t catch me here it depends on what you really do) than VBA.
The Contoso University sample web application demonstrates how to create ASP.

When you edit an instructor record, you want to be able to update the instructor's office assignment. Now you'll enhance the Instructor Edit page by adding the ability to change course assignments using a group of check boxes, as shown in the following screen shot: The relationship between the navigation property.
The grater the amount of screen changes the bigger the impact will be. Other application settings that can make a difference to execution time are Calculation and Event handling. Enable Events = False ' Code here Clean Up: On Error Resume Next Application. Calculation = xl Calculation Automatic Application. Enable Events = True Exit Sub EH: ' Do error handling Go To Clean Up End Sub Sub test Screen Updating() Dim i As Integer Dim numb Switches As Integer Dim results As String 'swap between sheets this number of times numb Switches = 1000 'keep track of time Dim start Time As Double start Time = Time 'swap between sheets 1/2 (need both sheets or this will crash) For i = 1 To numb Switches Sheets(1 (i Mod 2)).
Use this code template as a starting point (the error handler ensures that these properties are turned back on at the end of the sub, even if it errors) Sub Your Sub() On Error Go To EH Application. Select Next i 'get results results = "Screen Updating not disabled: " & Format(Time - start Time, "hh:mm:ss") & " seconds" start Time = Time 'scenario 2 - screenupdating disabled Application.
When I started reading more into improving the efficiency of your code I understood what it was for but how much of an effect does Turning off screen updating will only make a difference to execution time if the code interacts with Excel in a way that causes changes to the screen content.

From my own test I find out that turning screen updating off and on takes about 15ms (tested in C# via Excel Interop).
The drop-down list sets the public Action Result Create() [Http Post] [Validate Anti Forgery Token] public Action Result Create([Bind(Include = "Course ID, Title, Credits, Department ID")]Course course) public Action Result Edit(int?

To provide data to the view for the list of check boxes, you'll use a view model class.
