Setting the calculation mode back to xl Calculation Automatic will automatically trigger a recalculation of the worksheet. Calculation = xl Calculation Manual You may notice that when your macros run, your screen does a fair amount of flickering.
This flickering is Excel trying to redraw the screen in order to show the current state the worksheet is in.
While I’m thinking about this stuff, I’d like to share a few simple tips for speeding up your Excel VBA code. So feel free to comment and share any other performance tips you may have.
Each time a cell that affects any formula in your spreadsheet is changed or manipulated, Excel recalculates the entire worksheet.
This saves time and resources, allowing your macro to run a little faster.
Part of this task involves speeding up a few of the macros in the workbook.
Be sure to think about our specific scenario and determine what will happen if your worksheet or workbook events are turned off while your macro runs.
Another opportunity for a performance boost can be found in Page Breaks.

The idea is to place Excel into manual calculation mode, run your code, and then switch back to automatic calculation mode.
Unfortunately, each time Excel redraws the screen, it takes up memory resources.
