ALGO=zstd

# Specifies the amount of RAM that should be used for zram

# based on a percentage the total amount of available memory

# This takes precedence and overrides SIZE below

PERCENT=60

# Specifies a static amount of RAM that should be used for

# the ZRAM devices, this is in MiB

#SIZE=256

# Specifies the priority for the swap devices, see swapon(2)

# for more details. Higher number = higher priority

# This should probably be higher than hdd/ssd swaps.

PRIORITY=100
