Sounds like a fair statement. Not sure what we can do about baseline memory requirements on boot.

Though I'm currently using jemalloc on a Standard 1x Heroku dyno (512MB ~ $25/mo) serving about 1.5 million requests/day and it averages 275MB of memory usage with a mean response time of 35ms.


Note that this is a standard Rails 5+ app using Sidekiq for background jobs. Currently processing about 50k jobs/day.

That's a very efficient Rails app, well done!
