1.通过goland进行性能分析
命令行：

go tool pprof http://localhost:6060/debug/pprof/profile?seconds=30
top -cum
web

在main程序中加入下面分析代码

"net/http"
	_ "net/http/pprof"

	runtime.SetMutexProfileFraction(1) //开启对锁调用的跟踪 mutex
	runtime.SetBlockProfileRate(1)     //开启对阻塞操作的跟踪
	// 启动pprof HTTP服务器
	go func() {
		log.Info("Starting pprof server on :6060")
		if err := http.ListenAndServe(":6060", nil); err != nil {
			log.Error("Failed to start pprof server:", err)
		}
	}()
