This is my first time hearing about zram. I tried looking into it myself but there's still some things I could find answers to. Are there any downsides to using zram, or is it something that I can set and forget about? If I were to be using compression tools, like 7zip, would I be able to use a higher dictionary size than I normally can, or would zram cause problems outside of potentially slower compression speeds?

Edit: I think I'm just going to test this myself. I've been reading more about zram and alternatives and it seems like there's conflicting information.
