I know there are some Excel wizards here on the board, so maybe they know an answer to this question.

I have to work with a pretty big Excel sheet on my laptop. This laptop is a HP Spectre X360 laptop, 2018 model with i7 CPU, 16 GB RAM and a 512GB SSD. Pretty good specs I would think.

Now, when I change the value of a cell in this particular Excel sheet, this doesn't always happen instantly. Sometimes it takes a few seconds for it to change. Same with changing the color of the cell. This is annoying.

What could be causing this? I already changed the energy settings to maximum speed when running on cable, so I don't think that is the problem. I also get the impression it worsens when I've been working for a while, and is better when I reboot the PC, making me think it's some kind of buffer that is getting filled up.

I'm stumped. Any ideas would be appreciated.

Thanks!
