• compressor - the algorithm used to compress memory pages.
• zpool - the kernel's zpool type.
• accept_threshold_percent - the threshold at which ZSwap would start accepting pages again after it became full.
• non_same_filled_pages_enabled - enable or disable accepting non same filled memory pages.
• exclusive_loads - enable or disable entries invalidation when memory pages are loaded from compressed pool.
• shrinker_enabled - enable or disable pool shrinking based on memory pressure.

Forwarding options

Create a configuration file:

[zswap]
enabled=Y
same_filled_pages_enabled=Y
max_pool_percent=60
compressor=lzo
zpool=z3fold
accept_threshold_percent=90
non_same_filled_pages_enabled=Y
exclusive_loads=Y
shrinker_enabled=Y

Start the application with the --config command-line argument:

sudo zswap-cli --config /path/to/zswap-cli.conf
