性能/内存优化 + 工具

net/http/pprof

import (
    "fmt"   
    _ "net/http/pprof" 
    "net/http"
    
)

go func() {
        http.ListenAndServe("localhost:6060", nil)
    }()

然后访问​​http://localhost:6060/debug/pprof/​​  就可以看到性能

 

2.可以自定义调试页面

import (
  "net/http"
  "net/http/pprof"
  "fmt"
  "bytes"
  log "github.com/thinkboy/log4go"
)
func SocketHelp(w http.ResponseWriter, r *http.Request) {
  var buf bytes.Buffer
  fmt.Fprintf(&buf, "num_symbols: 1\n")
  w.Write(buf.Bytes())
}

// StartPprof start http pprof.
func Init(pprofBind []string) {
  pprofServeMux := http.NewServeMux()
  pprofServeMux.HandleFunc("/debug/pprof/", pprof.Index)
  pprofServeMux.HandleFunc("/debug/pprof/cmdline", pprof.Cmdline)
  pprofServeMux.HandleFunc("/debug/pprof/profile", pprof.Profile)
  pprofServeMux.HandleFunc("/debug/pprof/symbol", pprof.Symbol)
  pprofServeMux.HandleFunc("/debug/pprof/socket", SocketHelp)
  for _, addr := range pprofBind {
    go func() {
      if err := http.ListenAndServe(addr, pprofServeMux); err != nil {
        log.Error("http.ListenAndServe(\"%s\", pprofServeMux) error(%v)", addr, err)
        panic(err)
      }
    }()
  }
}
