我想知道为什么我的django网站(gunicorn 4工作人员)在重载下很慢,我做了一些分析http://djangosnippets.org/snippets/186/没有任何明确答案所以我从头开始一些负载测试ab -n 1000 -c 100 http://localhost:8888/
一个简单的Httpreponse("hello world")没有中间件==> 3600req/s
带有中间件的简单Httpreponse("hello world")(缓存会话,缓存身份验证)==> 2300req/s
一个简单的render_to_response只打印一个表单(缓存模板)==> 1200req/s(响应时间除以2)
一个简单的render_to_response,包含50个memcache查询==> 157req/s
Memcache查询应该比这快得多(我正在使用PyLibMCCache)？模板渲染是否与此结果一样慢？
我尝试了不同的分析技术但没有任何成功.

real-time priority …我正在尝试使用http://code.google.com/p/oauth-python-twitter在appengine(python)中实现"twitter oauth" .
我使用以下代码将用户重定向到twitter:
twitter = OAuthApi(CONSUMER_KEY, CONSUMER_SECRET)
request_token = twitter.getRequestToken()
response.set_cookie('request_token', request_token.to_string())
signin_url = twitter.getAuthorizationURL(request_token)
return redirect_to(signin_url)
用户成功重定向,但当他在我的应用程序中返回时,我收到以下错误:HTTP错误401:未经授权
File "/base/data/home/apps/app/controllers/users.py", line 46, in authenticate
access_token = twitter.getAccessToken()
File "/base/data/home/apps/app/lib/python/oauthtwitter.py", line 183, in getAccessToken
token = self._FetchUrl(url, no_cache=True)
......
File "/base/python_dist/lib/python2.5/urllib2.py", line 506, in http_error_default
raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
当我尝试获取访问令牌时发生错误.
request_token = request.cookies['request_token']
token = oauth.OAuthToken.from_string(request_token)
twitter = OAuthApi(app_globals.CONSUMER_KEY, app_globals.CONSUMER_SECRET, token) # everything works good
access_token = twitter.getAccessToken() # then, i receive the error.
任何的想法？谢谢!
