- Pre-fork 'processes.spare' application processes; - fork more processes to keep 'processes.spare' idle processes; - fork on-demand up to 'processes.max' count; - scale down idle application processes above 'processes.spare' after 'processes.idle_timeout'; - number of concurrently started application processes also limited by 'processes.spare' (or 1, if spare is 0).
