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)).

Free Excel Help One drawback with recorded macros in Excel is that the code produced is often very inefficient.This means that the Excel screen can look like it has "gone crazy" while the macro is running.

One thing you may want to do with your macro to make it run faster and to prevent distracting flashes on the screen is to turn off screen updating while the macro is running.

This tip (9151) applies to Microsoft Excel 2007, 2010, and 2013.

You can find a version of this tip for the older menu interface of Excel here: Turning Off Screen Updating.

From my own test I find out that turning screen updating off and on takes about 15ms (tested in C# via Excel Interop).

Keep that on mind if you will execute anything which would take less time.

By setting Screen Updating to False at the Start of the macro, you will not only stop the constant screen flickering associated with recorded macro, but also greatly speed up the execution of the macro.
