from tornado.options import define, options

from tornado import gen
from tornado.concurrent import run_on_executor
from concurrent.futures import ThreadPoolExecutor

# 定义端口为9090
define("port", default=9090, help="run on the given port", type=int)


# 单线程测试
class SanyaHelloHandler(tornado.web.RequestHandler):
  # get 函数
  def get(self):
    time.sleep(0.5)
    self.write('Hello from Sanya!')

# 多线程测试
class ShanghaiHelloHandler(tornado.web.RequestHandler):
  executor = ThreadPoolExecutor(4)

  @gen.coroutine
  def get(self):
    result = yield self.doing()
    self.write(result)

  # 使用tornado 线程池
  @run_on_executor
  def doing(self):
    time.sleep(0.5)
    return 'Hello from Shanghai!'


# 主函数
def server():
  # 开启tornado服务
  tornado.options.parse_command_line()
  # 定义app
  app = tornado.web.Application(
      handlers=[(r'/sanya', SanyaHelloHandler),
           (r'/shanghai', ShanghaiHelloHandler)
           ],  # 网页路径控制
     )
  http_server = tornado.httpserver.HTTPServer(app)
  http_server.listen(options.port)
  http_server.start()
  tornado.ioloop.IOLoop.instance().start()

server()

对上面的程序做个简单说面：
