PRTG and Large Installations

PRTG features a powerful web interface which is realized with a lot of scripting and connections to the PRTG core server that are realized in the background to provide a nice and speedy user experience. However, with installations of several thousand sensors, especially for 4,000 sensors and more, you should turn on the Speed Mode to remain fast response times within the web interface (Setup | System Administration | User Interface ("System & Website" in older PRTG versions) --> Performance Strategy setting). On large installations > 8,000 sensors, we experienced responses coming in up to 50% faster.

What the Speed Mode Does

When enabled, the speed mode changes the following settings:

  • Hides all menu sub-items which would usually show the device tree structure, for example, the By Group entry in the Sensors menu. Usually, PRTG processes the whole device tree if you open this menu to generate the tree structure; in speed mode, all sub-menus are removed to avoid this tree iteration.
  • Folds up all items in the device tree by default: All devices are collapsed in the normal tree view (i.e., no single sensors will be shown) unless you have opened them.
  • Hides all mini graphs on Overview tabs of devices.
  • Does not show open Tickets next to the sensor status overview bar.
  • Monitoring data display may be delayed for up to one minute (on the web interface only). Usually, PRTG calculates in the background the display of sensor states every 5 seconds for every user. The delay helps to reduce the load.
