How to improve API performance in the Go Echo framework

Introduction

Echo is a high-performance Go web framework that provides many out-of-the-box features to optimize API performance. This article will introduce some techniques to help you improve the response time and throughput of your API using the Echo framework.

Use middleware to cache responses

Caching is an effective way to improve API performance. Echo provides a middleware cache that caches responses and generates responses only on the first request. This is especially useful for frequently accessed API paths.

func main() {
    e := echo.New()

    // 缓存所有请求 10 分钟
    e.Use(middleware.Cache(10 * time.Minute))

    // 路由到你的 API 处理程序
    e.POST("/", yourAPIHandler)

    // 启动服务器
    e.Start(":8080")
}

Optimize database queries

Database queries are a common bottleneck in API performance. Echo comes with a db package to simplify database interaction. It provides several features to improve query speed, such as bulk inserts and pooled connections.

func yourAPIHandler(c echo.Context) error {
    db, err := mysql.Open("mysql", "user:password@/database")
    if err != nil {
        return err
    }
    defer db.Close()

    // 池化连接
    db.SetMaxIdleConns(10)
    db.SetMaxOpenConns(100)

    // 批量插入
    stmt, err := db.Prepare("INSERT INTO users (name, email) VALUES (?, ?)")
    if err != nil {
        return err
    }
    defer stmt.Close()

    // 批量插入 100 个用户
    for i := 0; i < 100; i++ {
        _, err := stmt.Exec("John Doe", "john.doe@example.com")
        if err != nil {
            return err
        }
    }

    return c.String(http.StatusOK, "OK")
}

Use gzip compression

gzip compression can significantly reduce the size of the response, thereby speeding up response times. Echo provides middleware.Gzip middleware to enable gzip compression.

func main() {
    e := echo.New()
    
    // 启用 gzip 压缩
    e.Use(middleware.Gzip())

    // 路由到你的 API 处理程序
    e.POST("/", yourAPIHandler)
    
    // 启动服务器
    e.Start(":8080")
}

Parallel processing

Under certain circumstances, parallel processing can improve API performance by processing multiple requests simultaneously. Echo comes with a middleware.Recover middleware that can be used to safely handle requests in coroutines.

func main() {
    e := echo.New()

    // 在协程中并行处理请求
    e.Use(middleware.Recover())

    // 路由到你的 API 处理程序
    e.POST("/", yourAPIHandler)

    // 启动服务器
    e.Start(":8080")
}

Practical Case

An online retailer built an API using the Echo framework to process orders from a mobile app. By implementing the above optimizations, they reduced order processing time from an average of 5 seconds to 1 second, significantly improving customer satisfaction and application smoothness.
