Performance Tuning and Benchmarking

Have you ever wondered how to determine if your Go code is performing at its best?

Benchmarks help you spot slow code and fix it. They also help you choose the best data structures and algorithms. By the end of this book, you will know how to write benchmarks that guide your engineering decisions.

Damn! It worked last week!

It takes ages for the newsfeed to load. Scrolling on the tablet is slower than normal. Applications are not starting as smoothly as they did a week ago.

You are getting frustrated. You recall the last change you pushed to production. No, it couldn’t be that simple change! Are you sure?

We are ready to experience the reality.

Enter the world of benchmarking and code archaeology!
