Is anyone else noticing that simply migrating an app from 12.6 to 2019 that the compiled apps are slow? I compiled an app in 12.6, then migrated the target to 2019 and compiled it there. A window in the 12.6 version that took 10 seconds to open takes 20 seconds in 2019. In some other areas I've seen as little as a 2 second increase using 2019. And during the beta, everything actually seemed to launch quicker than their 12.6 counterparts.

Is anyone else having any issues like this?

I think something is else is going on here because 1) PB 2019 is built from the PB 12.6 code base, and 2) we don't have any significant complaints about any performance regressions.

Hi Richard;

  FWIW:  I have not noticed any specific application performance issues in PB2017/2019 vs 12.6. However I did find one exception to that and, it seems to revolve around using the OLE-DB DB driver (very slow against SQL Server) in my testing and for some Appeon customers. However, changing the PB Apps to use either an  SNC or ODBC DB Client connection seems to cure that performance issue.

Regards ... Chris

Alright, that basically answers my question then. If it's just me, I'm clearly doing something wrong. Thanks!

Try completely regenerating all the PBLs again and also test on another computer to make sure it is not something machine-specific.

That's basically what I intend to do. I've got a Windows 7 machine next to me I intend to try it on as well, and I'll take it and try it in 2017R3 as well just to compare.
