How do I use trace tool to analyze latency?

Go's trace tool provides a robust way to analyze latency in your applications. By using trace, you can visualize where time is being spent in your Go programs, helping you to optimize performance effectively.

Using Go Trace Tool

To use the trace tool, you need to include the `net/http/pprof` package and then start a tracing session. Here's a simple example:

package main import ( "net/http" _ "net/http/pprof" "log" "time" ) func myHandler(w http.ResponseWriter, r *http.Request) { time.Sleep(2 * time.Second) // Simulate latency w.Write([]byte("Hello, World!")) } func main() { go func() { log.Println(http.ListenAndServe("localhost:6060", nil)) }() http.HandleFunc("/", myHandler) log.Println("Starting server on :8080") log.Fatal(http.ListenAndServe(":8080", nil)) }

After running your Go application, you can access the trace at http://localhost:6060/debug/trace.
