When choosing a web framework, I pretty much have eyes set on Tornado. But I heard good things about Flask and Gevent. So I tested the performance of each and combinations of the three. I chose something just a little more advanced than a "Hello World" program to write - one that use templates. Here are the codes:
| import os | |
| from gevent import monkey | |
| from socketio.server import SocketIOServer | |
| from flask import Flask, request, render_template | |
| from werkzeug.debug import DebuggedApplication | |
| monkey.patch_all() | |
| app = Flask(__name__) |
