Long-lived JVM applications memory usage tuning

A few days have passed since the last blog post about jvm memory usage monitoring tools, and I have learned so much about patterns of JVM memory usage and magic flags to use to influence it. I still can’t call myself an expert, but judging from the corpus of stackoverflow posts about jvm and memory, at least I’m not totally clueless. :-)

EDIT : this post has now been further extended and published on the newly published Kahoot engineering blog.
