I am using Excel 2013 with a simple workbook. It contains ~30 sheets, and ~80 rows and ~20 columns per sheet, filled with numbers, and the sum of the rows of one sheet is used as the first cell of the column in the next sheet.
If I open the file freshly and move a cell within a sheet, Excel 2013 takes about 30s to do the task, where Excel 2007, with the same file and the same cell to move does it instantly.
I already disabled the animations and checked the graphics card, which were causes for some Excel 2013 performance issues.
How can I speed things up in Excel 2013?
