Hello,

we migrated our app from PB11 to PB2022 R2 3356 a few month ago. 

Some (not all) of our users are complaining about the new speed of our app.

The more windows are opened, the slower the entire software becomes.

If there is one window open, it takes two seconds to open a special test window.

If there a two windows open, it takes 15 seconds to open the same test window again.

Another problem: If the user clicks on a other app in the task bar windows switches to this app immediately without any loss of time. Trying to get back to the Powerbuilder app takes a longer time. This time depends on the number of opened windows in the app. It seems that nothing is happening and after a while the main window of the app appears. While waitung the cpu goes up. This only happens at a few customer, but than on all pc. 

I checked the task manager, GDI, memory, cpu. No abnormalities

Any idea?

Thanks for your advice/help

Marco
