In my experience from using a zram + on-disk swap setup, performance is only good until the zram swap gets filled up. Then performance goes to hell because you'll be functioning primarily on your on-disk swap while your zram swap just acts as deadweight sitting around taking up memory. What I usually did at that point was to swapoff the zram swap to force everything into the on-disk swap, rmmod, and re-create the zram swap again to get free zram swap space. I don't think it's a good idea to make this default. -- Kind regards, Loong Jin
