package main

import (
	"fmt"
	"time"

	"github.com/go-redis/redis"
)

func main() {
	start := time.Now()
	client := redis.NewClient(&redis.Options{
		Addr: "127.0.0.1:6379",
	})
	err := client.Ping().Err()
	if err != nil {
		panic(err.Error())
	}
	for i := 0; i < 1000000; i++ {
		now := time.Now()
		nowStr := fmt.Sprintf("%d-%d-%d %02d:%02d:%02d", now.Year(), now.Month(), now.Day(), now.Hour(), now.Minute(), now.Second())
		client.LPush("log", nowStr+" 200 success laskdjflaskjdflkjasdl")
	}
	fmt.Println(time.Since(start))
}

　　

package main

import (
	"fmt"
	"os"
	"time"
)

func main() {
	file, err := os.Create("test.log")
	if err != nil {
		panic(err.Error())
	}
	start := time.Now()
	for i := 0; i < 1000000; i++ {
		now := time.Now()
		nowStr := fmt.Sprintf("%d-%d-%d %02d:%02d:%02d", now.Year(), now.Month(), now.Day(), now.Hour(), now.Minute(), now.Second())
		fmt.Fprintln(file, nowStr, "200", "success", "", "laksjdflkjsdal")
	}
	fmt.Println("time:", time.Since(start))
}

　　

不对时间进行格式化处理时

对时间进行格式化处理后

 

可见redis和直接的fmt输出到文件，速度差了十倍左右

但用redis存日志查起来比较容易查，还可以将日期附加到key里区分每一天的日志，具体用文件存储还是redis按需求来
