Hi, jemalloc 4.1 has been released https://github.com/jemalloc/jemalloc/releases/tag/4.1.0 a new feature is "Implement decay-based unused dirty page purging" https://github.com/jemalloc/jemalloc/issues/325 I'll try to give it a try next month on a new test cluster with jewel to see if memory usage vs tcmalloc has lowered.
