- Memory
  - Debugging hidden memory leaks in Ruby - "This article covers tools and tricks you can use to attack leaks that you can not easily introspect in Ruby. In particular I will discuss mwrap, heaptrack, iseq_collector and chap." by Sam Saffron (2019-10-15) 🇺🇸
  - What causes Ruby memory to bloat - How memory allocation works in Ruby and how to improve it with malloc_trim API. 🇺🇸
  - The Definitive Guide to Ruby Heap Dumps, Part I - “When you can’t reproduce memory bloat, here’s how to work with a heap dump.” by Richard Schneeman (Last updated: 2017-06-19) 🇺🇸

Official Ruby bugtracker notes
- Memory Improvements
  - Introduce malloc_trim(0) in full gc cycles - Per Hongli's excellent article it looks like malloc_trim can help tremendously with memory bloat issues. 🇺🇸
  - set M_ARENA_MAX for glibc malloc - Not everybody benefits from jemalloc and the extra download+install time is not always worth it. Lets make the user experience for glibc malloc users better, too. 🇺🇸
  - Use jemalloc by default?
