How to calculation memory in F5.

Hi,

I would like to know how the F5 calculation it's memory cause when I use command 'tmsh show sys performance system detail' I got the following images attached.

you can look at yellow text (other memory used in percentage) it's about 54% from all memory in F5. I would like to know what is the formular to calculation that number?

If you look at the images in the section memory breakdown Other used is just 6.8GB/50GB it's about 13.5% of all memory.

Thank you.
