How about adding a fomula to allocate memory like this? #34

There is no need to split via cores as zram is multistream and all cores can access a single zram device. You can add as much ram to zram as you wish and because application varies so much there isn't a formula apart from 50-25% is prob a good initial guestimate. Disk size is very dependent on alg chosen to expected compression.

I am sorry, I mean this line. mem=$(( ($totalmem / $cores) 1024 )) for example, 50% disksize mem=$(( ($totalmem /2) 1024 ))

now,we can set disksize as we like without fomula.

You can but zram-config runs a ztab so multiple devices and disks can be setup. Its zram-config which has multiple uses for zram and not just zram-swap. If it was just zram-swap then I would agree
