In this chapter, we focused on quick wins for increasing the overall performance for our application, by reducing impact on our underlying application's bottlenecks, namely our database.

We've implemented caching at the file level and described how to translate that into a memory-based caching system. We looked at SPDY and HTTP/2, which has now become a part of the underlying Go net/http package by default.

This in no way represents all the optimizations that we may need to produce highly performant code, but hits on some of the most common bottlenecks that can keep applications that work well in development from behaving similarly in production under heavy load.

This is where we end the book; hope you all enjoyed the ride!
