Sorry not a Doctor Who fan. It's way too convoluted a plot for me. :-)

Exactly my point. It's like saying that you are conserving the water in
your house by using more water.

Am I the only one who thinks that idea is crazy ?

Why page out to RAM ? You are still blocking up RAM that other applications
could still have used.

I see swap as means by which RAM is freed up by the kernel writing out
pages to the disk.

But what you are saying is that if I have 8 GB of RAM and let's say 3 GB is
actually full of zram swap pages, then, by that logic, applications will
have 3GB less RAM to operate than if the kernel had written out to disk. I
mean the RAM is still BEING USED.

Am I correct ? Do you see why this may not be a good idea ?
