Thank you Didier! Would you mind to put your exact configuration here?

Anyway, i went a bit further and around the compressed ram theme.
Given, that i probably will keep the harddrive swap partition
(as i said: for hibernation/s2disk) would it be more useful to use
zswap instead (zswap needs a physical swap device)? And to set the
percentage of ram given to zswap pretty high? (Activate zswap would be
some lines in the bootloader).

So, using tmpfs as parazyd pointed out, would go to be swapped early
into the compressed swap in ram, when there is no more uncompressed ram
available. Or is it ingenuous thinking?

If i understand correctly, zswap will, when it really comes to the
limits swap out the oldest swap pages to the "pysical" swap device,
zram would kill them (?).

Cheers.
