Non-zero values for --workers activates Multiprocessing.

Multiprocessing increases stability, makes somewhat better use of computing resources and can be better monitored and resource-restricted.

  • Number of workers should be based on the number of cores in the machine (possibly with some room for cron workers depending on how much cron work is predicted)
  • Worker limits can be configured based on the hardware configuration to avoid resources exhaustion


multiprocessing mode currently isn’t available on Windows


Hidden feature of Multiprocessing is automatic run gevent process for longpolling support.

Longpolling is an extra proccess, i.e. if you have --workers=2 then you will get 2 worker processes and 1 gevent process
