Dirty to used ratio in mongostat results

The lectures indicate that a significant mismatch between dirty and used memory percentages signals that there isn’t enough memory available for the WiredTiger storage engine to perform optimally.

After the lecture though, I’m unclear as to why that is. I was hoping to get a more in depth explanation from someone here, as I have been unable to find a satisfying one elsewhere.

Thanks
