it took too much time to build, even 5 minutes, but program is relatively small!, i don't know how to troubleshoot it and fix it, It's been bothering me for a long time.

you can use go build -x ... View the build process to see which steps take the most time, I guess it’s because downloading dependencies is too slow.
