If the percentage of available memory to total memory on the system drops, the tool will free memory till either the desired percentage is achieved or it runs out of memory to free. +.Pp +.Ar -S +Simulate memory pressure on the system by placing it artificially for <sleep_seconds> duration at the "warn" or "critical" level. +.Pp +.Ar -s <sleep_seconds> +Duration to wait before allocating or freeing memory if applying real pressure.
