Question
Does pega 7.2.2 require more JVM heap than 7.1.8
Hi,
We have an application running with similar load on Pega 7.1.8 and 7.2.2 . The application on the two versions is not identical but 80% same. Application on 7.1.8 consumes 2 GB heap with 4 GB set as max and the application on 7.2.2 use 5.4 GB heap with 6 GB set as max. both have 2 GB min set. GC happening properly. Does Pega 7.2.2 require more JVM heap than 7.1.8 ?? Any recommendations or suggestions on the heap recommendations for 7.2.2. Observed huge caching happening with 7.2.2 during load test.
Hi,
I doubt there is any specific difference as such
Based on server you can check in installation guide

I don't think this suggestion has changed over the period and heap size actually depends on the load testing results

Hope this clarify your doubts
