am i right that you can create zswap block devices and mount them like with zram? (eg. mounting /var/tmp)
zswap is a "front swap", it needs a backing swap to function that's crucial to the design. It automtically goes in front of all the swaps you have enabled.
You could probably put the backing swap on a loop device on a tmpfs, but I don't know how it will handle the loopback. It's a better idea to put it on disk. It can be a slow or write-limited disk, it will not get used much. You definitely should not use zram and zswap at the same time.
damn. when i do try out zswap i'll try and do this. but i do a lot of compiling and i prefer not to do all those reads and writes on my hard drive, so i will be sticking with zram for now.
thanks for the advice! it was hard for me to understand the differences at first when i first started looking at them so your comments are helpful.
woah thanks! i always thought zram was a better solution than zswap but i'll give zswap a try when i get time.
