Hands-On High Performance with Go

Real-world benchmarking

While you are running the benchmarks in this book, be sure to remember that benchmarks aren't the be-all and end-all for performance results. Benchmarking has both positives and drawbacks:

The positives of benchmarking are as follows:

• Surfaces potential problems before they become unwieldy
• Helps developers have a deeper understanding of their code
• Can identify potential bottlenecks in the design and data structures and algorithms stages

The drawbacks of benchmarking are as follows:

• Needs to be completed on a given cadence for meaningful results
• Data collation can be difficult
• Does not always yield a meaningful result for the problem at hand

Benchmarking is good for comparison. Benchmarking two things against one ...
