Matz declared that the next major version of Ruby is going to be 3x faster than Ruby 2. But how can we make a software 3x faster? Can we do that for Rails?
In this session, we will discuss the ways to survey performance hotspots in each layer of the framework, tuning techniques on the performance issues, and some actual works that you can apply to your apps.
Topics to be covered:
Speeding up DB queries and model initialization
View rendering and template lookup
Routes and URLs
Object allocations and GC pressure
Faster Rails boot and testing
Asset Pipeline tweaks
