What impacts runtime page load performance? How can it be improved?

I want to know how can i improve the load time for each page when i run a deployed project on plant scada runtime

Hi sansuthan singarasa ,

There could be a number of factors that influence the speed at which pages load in runtime, namely:

- Extensive use of Cicode on the page (that is blocking)

- Large number of alarm count calls used on the page or objects

- The speed at which IO data is polled and how responsive your data source is (PLC, RTU, database)

- The network speed that your SCADA runs on

- The hardware that hosts the Plant SCADA runtime (is it under load or matched for the task at hand)

There could be many other factors, but those are probably a place to start.

Your could add some logging to the button that calls the page, the page entry and the page load to get some more information about how long it is taking. What is the CPU usage like on the machine at the time of loading a page?

I'd recommend reaching out to AVEVA support to discuss this further.

Kind regards

The following option can have impact on initial page display performance as well:
[Animator]FastDisplay

The default value is 1.  If you have set this to 0, in your INI file, or your deployed Profiles then initial page display can be slower, and depending upon the graphical complexity, (especially if involving lots of genies, could cost up to 2 seconds.

Thank you for the help

Thank you i will give that a try and see
