We are working in PB19/Microsoft SQL Server 2014 (SP2-CU7) (KB4032541) - 12.0.5556.0 (X64)
Aug 17 2017 12:07:38
Copyright (c) Microsoft Corporation
Enterprise Edition (64-bit) on Windows NT 6.3 <X64> (Build 9600: )

application is deployed in citrix environment with PB application exe and pbd files and also PBVM. This application is running extremely slow and hanging (not responding message on window title) but it is working okay without any performance in local environment.

there is no issue from performance perspective as per infrastructure team.

Need solution asap.

HI Romesh,

It looks like a difficult problem - though I think Armeen might be right in saying it's a Citrix configuration problem - questions:

- Is the database the same one when running locally or on citrix? (thinking of maybe missing indexes)

- How do other applications behave? Are they also slow for users?

- How is the internet connection that users are using?

Regards

Does the PB app use Themes?

Are you using any kind of animations in for example the opening of your windows?
If you set an "OpenAnimation" with x milliseconds of AnimationTime, that would be pretty slow on Citrix as it has to send the "drawing" of the window every x milliseconds over the network.

Another thing you could check is if you have a "TimerInterval" (refresh) different than 0 on datawindows.

regards

Is it extremely slow to do everything or just specific functionality?

We have lots of customers using Citrix on Windows Server 2012.  If everything is slow then it is problem with your Citrix environment/configuration.

The first thing to asses is whether the modules have "common Ancestors". If so, where those reside should be 1st in the library list. BTW: If your App has < 20 PBL's, then this performance tip would probably not apply to your App.

Hi Chris,



our application contains around 80 modules with 80 separate pbl files. these modules are accessed through .NET menu application as exe files.



We deployed each exe and pbd file in a single folder that contains PB19 VM and other necessary files.



Thank you.



Best Regards,

Romesh

With 80 PBLs, the library reordering from H=>L use could help. Maybe worth a quick try (food for thought). ;-)
