Golang framework document performance optimization

To optimize the performance of Go framework documents in highly concurrent applications: cache parsing results to avoid repeated parsing. Use the embedding mechanism to embed document content into code to reduce I/O. Employ parallel processing to process large volumes of documents.

Go framework document performance optimization

In high-concurrency applications, the performance of the framework document is crucial. This article will discuss how to improve the performance of Go framework documents through optimization techniques, and provide practical cases to illustrate.

1. Cache parsing results

Avoid repeatedly parsing the text content of the document. Use sync.Once or a similar mechanism to cache parsing results to avoid reparsing on subsequent requests.

var docOnce sync.Once
var docContent string

// GetDocContent 返回文档内容。
func GetDocContent() string {
    docOnce.Do(func() {
        docContent = doParse(".") // 解析文档内容
    })
    return docContent
}

2. Reduce unnecessary I/O

Document content is usually stored in files. Frequent file I/O can significantly impact performance. Consider using a mechanism such as Embed to embed the document content into the code to avoid reading the file.

//go:embed doc.md
var docContent string // 文档内容嵌入到代码中

3. Use parallel processing

If you need to process a large number of documents, you can use parallel processing to improve efficiency. Use sync.WaitGroup or similar mechanism to ensure all handlers complete their tasks.

var wg sync.WaitGroup
var docContents []string

// ParallelParse 并行解析文档。
func ParallelParse(paths []string) {
    for _, path := range paths {
        wg.Add(1)
        go func(path string) {
            defer wg.Done()
            docContents = append(docContents, doParse(path))
        }(path)
    }
    wg.Wait()
}

Practical case: Optimizing Gin framework documentation

Gin is a popular Go RESTful API framework. The following code demonstrates how to apply these optimization techniques to improve the performance of Gin documents:

import (
    "embed"
    "sync"

    "github.com/gin-gonic/gin"
)

var docOnce sync.Once
var docContent string

//go:embed doc.md
var embeddedDoc string // 文档内容嵌入到代码中

func registerDocs(r *gin.Engine) {
    r.GET("/docs", func(c *gin.Context) {
        docOnce.Do(func() {
            docContent = embeddedDoc // 直接从嵌入的内容中获取
        })
        c.String(200, docContent)
    })
}

Conclusion

By implementing these optimization techniques, it is possible to improve the performance of Gin documents without affecting accuracy. Significantly improve the performance of Go framework documents. Proper use of caching, reduced I/O, and parallel processing can help optimize document serving, thereby improving application responsiveness and throughput.
