我刚在阿里云申请机器(4核4G内存硬盘是SSD的)，压测了一下，QPS都是1.1万以上(go-stress-testing 单核cpu)

这里有压测示例，可以参考一下:

简单的修改一下，然后QPS可以达到1.8W， (go-stress-testing 双核cpu)，机器性能更高这个数值会更高
这里需要让出双核给go-stress-testing使用
代码修改处

        # 这里默认设置1，因为设置为1已经可以达到1W多QPS了，一般的环境压测已经够用了
	runtime.GOMAXPROCS(2)

webSevers 使用两核

package main

import (
    "log"
    "net/http"
    "runtime"
)

const (
    httpPort = "8088"
)

func main() {

    runtime.GOMAXPROCS(runtime.NumCPU() - 2)
    hello := func(w http.ResponseWriter, req *http.Request) {
        data := "Hello, go-stress-testing! \n"

        w.Header().Add("Server", "golang")
        w.Write([]byte(data))

        return
    }

    http.HandleFunc("/", hello)
    err := http.ListenAndServe(":"+httpPort, nil)

    if err != nil {
        log.Fatal("ListenAndServe: ", err)
    }
}

压测结果
