Sorry not a Doctor Who fan. It's way too convoluted a plot for me. :-)
Although in this case, it does take up more space the more you stuff in
it, but it holds more than the space it takes up.
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 ?
The RAM pages that need to get paged out get compressed and kept in
memory. I suppose you could consider that my system with 12GB of RAM
and 12GB of zram configured could become an 8GB system with 12GB of used
swap. 20GB of virtual memory but still not using the disk.
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 ?
