[webmin-l] memory display information-2

[Andrea L. <and...@fr...>]

I tried to turn of swap, removing /etc/fstab entry for that
 
after reboot, I can read:

Now it is clear that I actually don't know what that last entry in the top
Swap line means !
I supposed it had something to do with swap, but actually my swap is off
....
So: what is cached ? and where is cached ? And how can I avoid this "cached"
?
I am really confused about this....
 
Thanks in advandce, 
Andrea
