# Application Cache Memory

Vagon Streams is designed to collect continuous feedback on the application performance and optimize it according to performance selection.

Each time you upload a new build to the Vagon Dashboard or switch performance groups (different GPU series), the system generates a virtual cache memory for the application.

After each visitor session, the system automatically collects application-generated shader & asset files and uses them for future sessions to optimize the application connectivity.

If the cache files are ready for an application, an "Optimized" badge will appear on its card.
