We have recently migrated hundreds of PowerBuilder applications to PowerServer and deployed them in AKS using Linux containers. After deployment in the customer environment, we observed slow performance.

To address this, we implemented several optimizations:

  • Caching master data in local memory
  • Using PowerServer merge statements to reduce multiple calls
  • Combining multiple SQL queries into a single stored procedure

These changes improved performance. However, the customer is now reporting slowness when launching the application. Their workflow involves frequently switching between rooms, which requires logging out of the current room and logging back into another. This process happens multiple times a day, making the startup time critical.

To further improve performance, we are considering caching master data on the server side instead of the client side. Since this requires a multi-session cache, we may need to use a third-party caching solution to store and retrieve data at application startup.

Our questions:

  1. Does PowerServer support server-side data caching?
  2. Does it integrate with Redis or similar caching solutions?
  3. If yes, are there any examples or best practices for implementing server-side caching in PowerServer?

Thanks & Regards,

Jeyakumar
