For years, people have been using jemalloc with ruby. There were various benchmarks and discussions. Legend had it that Jemalloc 5 didn't work as well as Jemalloc 3.

Then, one day, hope appeared on the horizon. @wjordan offered a config for Jemalloc 5.

Ubuntu/Debian

FROM ruby:3.1.2-bullseye
RUN apt-get update ; \

If your master.key has been compromised, you might want to regenerate it.

No key regeneration feature at the moment. We have to do it manually.

Copy content of original credentials rails credentials:show somewhere temporarily.
Remove config/master.key and config/credentials.yml.enc
Run EDITOR=vim rails credentials:edit in the terminal: This command will create a new master.key and credentials.yml.enc if they do not exist.
Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
Add and Commit the file config/credentials.yml.enc

Requisites:

Create a free account at https://www.mailgun.com/
Save your API Key as a environment variables: export MAILGUN_API_KEY=key-1111111111111111111111111

As example, I will use a model named Request.
