How Can I Optimize Go Builds for Faster Compilation Using Caching and Reuse?

Go Build Optimization for Cache and Reuse

Go build presents a speed bottleneck for certain programs, particularly those involving CGO invocations. For efficient development, caching existing builds can dramatically reduce rebuild time.

One commonly used approach is Makefiles with % rules. However, according to the language designers, Go's build system eliminates the need for Makefiles.

An alternative solution is the go build and go install commands, which are scheduled to receive significant speed enhancements in Go 1.10 (Q1 2018). These enhancements include a cache for built packages and metadata that defaults to the user cache directory.

Using $GOCACHE, developers can specify a custom cache location. The cache will contain past build steps, allowing subsequent builds to skip unnecessary steps and reuse existing products.

By default, "go test" and "go build" commands leverage the cache to perform fast and incremental builds. This replaces the need for using workarounds like "go test -i" or "go build -i."

It's important to note that go install does not install dependencies for named packages. Please refer to the official documentation for further clarification.
