 WebHMI uses Comet technology to push register value changes into browser at the end of every scan where it was changed. Sometimes register value changes too often. To save traffic and resources you can throttle send interval. You can tell WebHMI send these update not often than some interval. This setting is adjustable between 100 ms. up to 5 sec.

+==== Override screen resolution ====
 Some devices’ OS, like smartTV, may report wrong resolution for the browser, lowering it for a convenient view. In most cases this is not desired behaviour in the monitoring systems, because the visualization is developed for the specific display resolution. Now you can force screen resolution to desired.

+===== Storage settings =====
+These settings affect storage scenario.
+  ***Disk**: For WebHMI,  use External disk settings. For other target platforms you may want to use one drive for both the system & storage volumes.
+  ***Limit log storage time & Log disk space limit** settings control when the log data will be automatically deleted from the database - either on aging above set storage time, or when free room on the volume will critically shrink.

+===== Services =====
+In this tab, you can switch on/off several services. Disabling services, that you won't need in the project frees up some OS resources what might be of use in very big projects where the WebHMI is heavily loaded.
+  ***FTP server**   - handles FTP requests to the WebHMI. [[ftp_server|Read more ...]]
+  ***MQTT server**  - enables local MQTT broker process   [[iot:tutorial:mqtt | Read more ...]]
+  ***Zabbix agent** - this one is for internal use and had been activly in use during early WebHMI installatoin commissioning purposes. May be switched off.
