Extremely slow performance in Excel
The excel performance is really really slow even in a blank file, it taks 12 seconds after you click the enter button.

I have experience extremely slow execution time, simple copying cells from one sheet to another in the same workbook, on versions 2012 and now 2101. So far, it appears there's no recognition nor care about this inferior performance, So far the only resolution is to completely remove the newer versions and reinstalling with an older version - v1902 or earlier.

Try turning off AutoComplete in the advanced Excel settings. This shouldn't make a difference in a blank sheet, but a huge difference in large sheets.
