Dear Jochen, Thanks for your answering. As you see, RAM for my system is about 20GB but cache being used is about 15GB and can increase in next time. Free RAM is slow, when I access my server, I see it more slowly. Do you have any exp for customizing graylog system. Please advise me for this case!!!. My server receive about 200msg/s.
