boot.zswap.acceptThresholdPercent
NixOS option
Threshold percentage at which zswap starts accepting pages again after the pool becomes full (1-100). This parameter provides hysteresis to prevent pool oscillation. When the pool usage drops below this threshold, zswap starts accepting new pages. Default is 90% as recommended by kernel documentation.
