Thanks for the video, the blue color terminal output is very hard to read 17:13 . ❤

Large memory allocations can cause performance issues, so those gems are useful to investigate and understand ruby memory allocations. Eg. When dealing with writing a large csv file from db.

Agains thanks for the really nice compilation of techniques😊 .

Hey thanks for this tutorial. It was super helpful to compare and describe the different ways we can debug Rails apps. I'm curious to learn more about marginalia. I could see it being useful for the apps I build professionally since they are quite robust and broken into multiple services.
