Today, we are kicking off a series of blogs on scaling Rails applications.

Ruby on Rails makes it easy to get started. However, if you want your application to scale, you need to answer questions like how many processes to have, how many threads, and whether the application is IO-bound or CPU-bound. What about connection pooling? Do you have pre-booting?

In this series, we will be looking at these questions more. The first blog is about understanding Puma, Concurrency, and the Effect of the GVL on Performance.
