"go build" Performance Degradation Post-Go Version Update
After updating Go to version 1.3, a notable concern arose when the "go build" command experienced a significant slowdown, with execution time increasing from approximately 4 seconds to over 45 seconds. This issue persisted despite the lack of any other system modifications. Disabling the virus scanner also proved ineffective.
Possible Explanations and Solutions:
- Dependency Recompilation: The issue may stem from dependencies being recompiled during each "go build" process. To address this, employ the command "go install -a mypackage" to rebuild all dependencies comprehensively.
- Outdated Object Files: Residual object files can contribute to compilation delays. To purge these files, navigate to and remove the "$GOPATH/pkg" directory.
- Incompatible Versions: Compiling with the "-x" flag provides insights into whether the toolchain is encountering incompatible version conflicts. This flag displays a breakdown of the compilation process.
The above is the detailed content of Why is 'go build' Significantly Slower After Updating to Go 1.3?. For more information, please follow other related articles on the PHP Chinese website!
Learn Go String Manipulation: Working with the 'strings' PackageMay 09, 2025 am 12:07 AMGo's "strings" package provides rich features to make string operation efficient and simple. 1) Use strings.Contains() to check substrings. 2) strings.Split() can be used to parse data, but it should be used with caution to avoid performance problems. 3) strings.Join() is suitable for formatting strings, but for small datasets, looping = is more efficient. 4) For large strings, it is more efficient to build strings using strings.Builder.
Go: String Manipulation with the Standard 'strings' PackageMay 09, 2025 am 12:07 AMGo uses the "strings" package for string operations. 1) Use strings.Join function to splice strings. 2) Use the strings.Contains function to find substrings. 3) Use the strings.Replace function to replace strings. These functions are efficient and easy to use and are suitable for various string processing tasks.
