Hello people,
I will not pretend that I know much about the way that Linux handles
memory, but I have a thought that might be of some use (I hope) to
somebody working on the virtual memory.
When we are about to run out of swap, why don't we then start
compressing all data in the swap partition(s), and compress any new data
before it's written to swap (and ofcourse decompress it when it's read
from swap). You would ofcourse need to keep track of the compression
ratio, so that as soon as we can stop using compressed swap we do so.
I know this does not solve the problem. But at least it might be able to
let the system live a little longer, or even make it survive the load.
I hope this will be of some use to somebody.
Best regards
Jesper Juhl
