Fra*_*cis 5 optimization performance scala go playframework
我正在 Scala Play 框架 2.5 和 golang 中对一个简单的 hello world 示例进行基准测试。Golang 似乎在性能上明显领先，我想知道如何优化 play 框架以提高性能。我正在使用以下内容进行基准测试
ab -r -k -n 100000 -c 100 http://localhost:9000/
我在生产模式下运行 play 2.5，在我的项目中随处使用默认配置。有人可以帮助我调整播放服务器的性能以获得最佳性能吗？我阅读了 default-dispatcher 线程池，但不确定要为我的电脑使用哪些设置。还有我可以检查的其他任何有助于提高性能的区域吗？
这是我的 Marchine 规格
Intel(R) Xeon(R) W3670 @ 3.20GHz 3.19GHz, 12.0 GM RAM, running windows 7 64-bit
请注意，我使用 sbt（clean 和 stage）在 prod 模式下就地运行服务器并执行在 target/universal/stage/bin/ 中找到的 bat 文件。这是播放的源代码
package controllers
import play.api.mvc._
class Application extends Controller {
def index = Action {
Ok("Hello, world!")
}
}
这是ab基准测试的结果
ab -r -k -n 100000 -c 100 http://localhost:9000/

这是 golang 的源代码
package main
import (
"fmt"
"net/http"
)
func handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, world!")
}
func main() {
http.HandleFunc("/", handler)
http.ListenAndServe(":8080", nil)
}
这是 golang 的 ab 基准测试的结果

提前谢谢你弗朗西斯
更新！
以下结果提高了性能，但我仍然对其他可以提高性能的想法感兴趣
package controllers
import play.api.mvc._
import scala.concurrent.Future
import play.api.libs.concurrent.Execution.Implicits.defaultContext
class Application extends Controller {
def index = Action.async {
Future.successful(Ok("Hello, world!"))
}
}
