Excel Slow Performance - Calculating (8 Threads)

If you experience slowness while working on your Excel workbook and you can see the calculating message appear at the bottom right of your Excel workbook. It could be due to you are using formula such as COUNTIF and your argument is to scan all the rows (e.g. A:A).
If your data do not occupy all the rows, then make it more explicit so that it scan only rows with data. If doing this is troublesome, you can just scope it such as it is big enough (e.g.A1:A800) to cover your case. Once this is done, you should not experience slowness as the scanning can be done faster.
