The basics of benchmarking Go applications | Smart Go

The video tutorial explains how to write benchmarks in Go to evaluate code performance. It covers the use of Go's standard library tools for creating and running benchmarks alongside test suites. The tutorial demonstrates benchmarking with a Fibonacci sequence example, comparing implementations using native integers and the math/big package. It details creating benchmark functions, running them with the Go test command, and analyzing results. The video also discusses profiling for CPU and memory usage, and suggests potential optimizations for performance improvement.
