Hello Valdis, thank you you for you reply. I'work for a big company as SAP partner and i responsible for SAP HANA and the infrastucture. My personal intrest is the memory managment. My impression was the same as you answerded. As you said i will try to figure out what the mm code is doing and try to find out what can we do better.
