[recurser]

I work on the project discussed in the article. We're running puma in clustered mode, with multiple workers per dyno and multiple threads per worker. 1GB is plenty in this context - each worker is pretty lightweight. At the time this was written we were running ~10 2x dynos, but we've since switched to 3 performance-m dynos with more puma threads/workers.

The main issue we were facing wasn't the hosting bill, but high (for us) traffic, that was leaking memory on every request. Under low traffic it was unnoticeable, but at peak load the leak would cause dyno memory to max out pretty quickly, which would cause timeouts and increase the traffic to other dynos, causing cascading failures. Having more memory available would definitely have made things a lot easier, but we would have run out eventually either way.
