我正在使用nginx在Google計算引擎上執行我的django項目。Django空白頁面需要2秒才能加載

我的看法文件，

from django.shortcuts import render_to_response 

def home(request): 
    return render_to_response('html/index.html',RequestContext(request))

和我的模板index.html文件

<html> 
<head> 
<title> Home </title> 
</head> 
<body> 
Wel come to my new project 
</body> 
</html>

在呼籲獨此頁面需要2.75秒到我的服務器上加載完全。

FFTB（等待時間）需要1.8秒此延遲是否存在任何配置問題？

請問您爲什麼需要很長時間，我的配置有什麼問題。

你用什麼從上游端口8000服務？ –

@DanielRoseman我沒有關於服務器端集成的想法。我已經使用了一些手冊來配置它。即使這個項目正在運行，檢查更新的文件。請告訴你建議我會檢查並通知你。 –

您已將nginx設置爲指向端口8000上的上游服務器。在那裏運行的是什麼？你必須有東西，否則你的應用程序根本就沒有響應。你在使用gunicorn？或者你（使用Django runserver）（如Yevgeniy提示）？如果是後者，你**絕對不能這樣做**。 –

用戶使用調試服務器與DEBUG = True設置運行django項目。它啓用了DEBUG工具欄 - 這非常慢。這是該設置的正常時間。如果你會禁用這個 - 我認爲一切都會好的。

如果你仍然有麻煩 - 我建議你檢查django調試服務器的響應時間（python manage.py runserver）。如果它更快，那麼問題是nginx配置，或者如果相同 - 你應該檢查與lineprofiler時間。

如果是生產配置 - 請勿在生產中使用調試服務器。您應該使用gunicorn或類似的東西來運行django項目。

即使調試是禁用它也需要相同的時間才能執行，而django調試服務器和nginx也差不多，差別不大。我會檢查線輪廓儀和gunicorn，讓你知道。 –

我已經使用了line prifiler，我在我的問題中附加了結果。請看看，讓我知道我還有什麼要做。 –

下一步應該是： 1.禁用社交認證中間件 2.切換到memcached或其他可用的內存緩存後端 3.檢查確實禁用了DEBUG設置（./manage.py shell;來自django.conf導入設置;打印settings.DEBUG） 4.在本地運行項目 - 可能是谷歌計算引擎的原因是什麼？）通常，django可以很好地處理這樣簡單的項目。 –
