Guide: Worker number calculation

    Rule of thumb : (#CPU * 2) + 1
    Cron workers need CPU
    1 worker ~= 6 concurrent users

cpu: 1 core (1 core 2 thread) Intel(R) Atom(TM) CPU N455 @ 1.66GHz
workers = 2+1

CPU time needs to be loonger to finish the task, we triple it.

Configuration:

workers = 3
;max_cron_threads = 2 ;default
;limit_time_cpu = 60 ;default
;limit_time_real = 120 ;default
max_cron_threads = 1
limit_time_cpu = 240
limit_time_real = 360

To install pos module, follow these sequence:

1. Inventory
2. Invoicing
3. POS
