Screen opening in Flexpendant

M Johnson

When I open a screen in the Flexpendant it takes around 20-25 seconds.

Switching between tabs takes around 5-6 seconds.

Respons from pressing a button around a second.

 

I guess it depends on the cpu load but what can be done about it?

Is there some of the controls tha takes extra process load? Signalbinding? Dropdown lists?

Hi Johnsson, 

I'll ask the developers if they can give some hints on some controls that are more likely than others to cause performance problems.

Can you tell us more about how your problem started? Is it a new application you are developing? Or is it an application in production where the the performance has slowly degraded over time?

Hi again,

we have heard about problems similar to the one you describe;

It appeared when a screen contained tab controls, and each tab page has controls on it. When moving between tabs, calls are made to activate and deactivate the controls bindings.

It is possible that the "unbinding" does not work correct and you will end up with lots of subscriptions to the same RAPID variables or I/O signals. Everytime you activate one of the tabs it will get worse.

Is this close to what you have done in your application?

Hi again Johnsson, I have not heard from you for a while and assume your problem has been resolved.
