Python Django在Heroku部署Gunicorn后性能下降

我正在和Heroku玩，以测试它对Django应用程序有多好

我创建了一个简单的项目，包括两个操作：

返回简单的hello world

生成图像并将其作为响应发送

我使用了

seake-c10-t30s

来测试Django开发服务器和gunicorn（都在Heroku上运行）。以下是我的结果：

简单的hello world

我用过
-Django 1.4
-Gunicorn 0.14.6
-文夫

为什么gunicorn这么慢

//更新
这两个测试都在Heroku环境中运行

dev server是指标准的django服务器-它可以由描述的

python manage.py runserver运行。
您必须进行设置，以了解问题的确切位置。
可能您的Internet连接速度是一个瓶颈？从Heroku下载数据显然比通过localhost移动数据慢（我假设django dev服务器在localhost上运行）。这可能解释了为什么对于Heroku来说，响应小（HelloWord）的基准测试同样快，而响应大（图像）的基准测试则慢。
设置是否相同？Django 1.4开发服务器默认是多线程的，gunicorn默认配置中只有一个同步工作程序。
这并不是那么简单，Django开发服务器是在Heroku运行的。我将遵循以下跟踪。谢谢你是对的，与10名工人一起管理gunicorn解决了我的问题。谢谢
