+From version 1.5.4 it is possible to use the parameter ``--file
+<zabbix_command_file>`` or ``-f <zabbix_command_file>`` to define a
+file with multiple ``zabbix-cli`` commands. 
+
+Some performance improvements get activated when executing
+``zabbix-cli`` in this way. The perfomance gain when running multiple
+commands via an input file can be as high as 70% when creating new
+hosts in Zabbix.

 One can also use the parameters ``--output csv`` or
 ``--output json`` when running ``zabbix-cli`` in non-interactive
 modus to generate an output in CSV or JSON format.
