Concurrency control strategy and performance optimization skills of http.Transport in Go language
In Go language, you can use http.Transport to create and manage clients for HTTP requests. http.Transport is widely used in Go's standard library and provides many configurable parameters, as well as concurrency control functions. In this article, we will discuss how to use http.Transport's concurrency control strategy to optimize performance and show some working example code.
1. Concurrency control strategy
The concurrency control strategy of http.Transport is mainly implemented through the two parameters MaxIdleConnsPerHost and MaxIdleConns. Among them, MaxIdleConnsPerHost represents the maximum number of idle connections enabled for each host (host), and MaxIdleConns represents the total maximum number of idle connections. By adjusting these two parameters, we can control the number of concurrent connections and thereby improve the performance of HTTP requests.
The following is a sample code that shows how to set the MaxIdleConnsPerHost and MaxIdleConns parameters:
package main
import (
"net/http"
"fmt"
"time"
)
func main() {
transport := &http.Transport{
MaxIdleConnsPerHost: 100,
MaxIdleConns: 1000,
}
client := &http.Client{
Transport: transport,
Timeout: time.Second * 10,
}
resp, err := client.Get("http://example.com")
if err != nil {
fmt.Println("請求失?。?quot;, err)
return
}
defer resp.Body.Close()
fmt.Println("請求成功！")
}In the above example, we created an http.Transport instance and set MaxIdleConnsPerHost to 100 and MaxIdleConns is 1000. This means that when we make a request to the same host, we can only open up to 100 connections at the same time; and when the total number of idle connections exceeds 1,000, the excess idle connections will be closed.
2. Performance optimization techniques
In addition to concurrency control strategies, we can also improve the efficiency of HTTP requests through other performance optimization techniques. The following are some feasible optimization solutions:
1. Enable connection reuse (Connection Reuse)
By default, http.Transport will use the Keep-Alive mechanism to reuse connections. This reduces the overhead of establishing and closing connections on each request. In actual use, we should set Transport's DisableKeepAlives to false to enable connection reuse.
transport := &http.Transport{
DisableKeepAlives: false,
}2. Enable Connection Pool
Connection Pool is a mechanism for managing and reusing connections. In the Go language, http.Transport has connection pooling enabled by default. We can adjust the size of the connection pool by setting the values ??of the MaxIdleConns and MaxIdleConnsPerHost parameters.
transport := &http.Transport{
MaxIdleConnsPerHost: 100,
MaxIdleConns: 1000,
}3. Enable the HTTP request pipeline mechanism (HTTP Request Pipelining)
The pipeline mechanism can reduce the delay between the request and the response. In Go language, we can disable compression through the Transport.DisableCompression parameter to reduce latency.
transport := &http.Transport{
DisableCompression: true,
}4. Enable streaming response of HTTP response (Streaming Response)
When processing a large amount of response data, we can reduce memory consumption through streaming response (Streaming Response). In the Go language, we can enable streaming reading by setting client.Transport.DisableResponseBuffering to true.
client := &http.Client{
Transport: &http.Transport{
DisableResponseBuffering: true,
},
}The above are some sample codes using http.Transport’s concurrency control strategies and performance optimization techniques. By properly configuring the parameters of http.Transport, we can optimize the performance of HTTP requests and improve the throughput of the program. I hope this article will help you with concurrency control and performance optimization in Go language development.

Performance optimization and horizontal expansion technology of Go framework?
Jun 03, 2024 pm 07:27 PM
In order to improve the performance of Go applications, we can take the following optimization measures: Caching: Use caching to reduce the number of accesses to the underlying storage and improve performance. Concurrency: Use goroutines and channels to execute lengthy tasks in parallel. Memory Management: Manually manage memory (using the unsafe package) to further optimize performance. To scale out an application we can implement the following techniques: Horizontal Scaling (Horizontal Scaling): Deploying application instances on multiple servers or nodes. Load balancing: Use a load balancer to distribute requests to multiple application instances. Data sharding: Distribute large data sets across multiple databases or storage nodes to improve query performance and scalability.
Nginx Performance Tuning: Optimizing for Speed and Low Latency
Apr 05, 2025 am 12:08 AM
Nginx performance tuning can be achieved by adjusting the number of worker processes, connection pool size, enabling Gzip compression and HTTP/2 protocols, and using cache and load balancing. 1. Adjust the number of worker processes and connection pool size: worker_processesauto; events{worker_connections1024;}. 2. Enable Gzip compression and HTTP/2 protocol: http{gzipon;server{listen443sslhttp2;}}. 3. Use cache optimization: http{proxy_cache_path/path/to/cachelevels=1:2k
