Python使用瓶子粘贴框架时发生断管错误

我使用瓶子框架实现WSGI请求和响应，由于单线程问题，我将服务器更改为PythonWSGIServer，并使用Apache bench进行测试，但结果是错误管道破裂，这与此问题类似。 我试过这个答案，但没有用

  Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/paste/httpserver.py", line 1068, in process_request_in_thread
    self.finish_request(request, client_address)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 323, in finish_request
    self.RequestHandlerClass(request, client_address, self)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 641, in __init__
    self.finish()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 694, in finish
    self.wfile.flush()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 303, in flush
    self._sock.sendall(view[write_offset:write_offset+buffer_size])
error: [Errno 32] Broken pipe

服务器代码如下所示，我不知道如何使用线程池改进连接

from paste import httpserver

    @route('/')
    def index():
        connection = pymongo.MongoClient(connectionString)
        db = connection.test
        collection = db.test
        return str(collection.find_one())

    application = default_app()
    httpserver.serve(application, host='127.0.0.1', port=8082)

这是因为WSGIServer是一个同步服务器，不适用于同时发送请求的高并发用户。为了绕过这些回退，可以使用很多第三方框架。其中最受欢迎的是格文绿条图书馆、龙卷风和奇瑞比。它们都基于事件驱动和异步方法，使它们能够处理多个并发用户
