On Android of course it depends on the configuration. I am running LineageOS 23 on an older device with 6GB of RAM as well and it would kill basically anything (making e.g. paying with a credit card a pain when you have to switch to the bank app to confirm a transaction). Had to adjust few variables for ZRAM control and now it's seamless.
