Why is

Slowed "go build" Performance After Go Upgrade

Recently, users who upgraded from Go 1.2.1 to 1.3 have reported significantly increased build times for "go build." This article explores potential causes and solutions for this slowdown.

Possible Culprits

One potential cause is the presence of dependencies that require recompilation at each build. This can be resolved by executing "go install -a mypackage" to rebuild all dependencies.

Another factor could be outdated object files in the "$GOPATH/pkg" directory. Deleting this directory will ensure that any older files do not interfere with the build process.

Diagnostic Tools

To gain insight into the build process, the "-x" flag can be used with "go build." This flag provides a detailed log of the steps involved and can reveal incompatibilities between toolchain versions.

Additional Tips

  • Disabling antivirus software may not always resolve the issue.
  • Ensure that the Go installation is up-to-date.
  • Experiment with different build tags to optimize the compilation process.
