1.uwsgi 性能测试
新建共用：test.py，代码如下：
from bottle import Bottle, run
app = Bottle()
@app.route('/hello')
def hello():
return "Hello World!"
if __name__ == "__main__":
run(app, host='localhost', port=8000)
执行命令：
uwsgi_python --http-socket=:8000 --workers=2 --wsgi-file hello.py --callable app 2>/dev/null
运行结果:
ab -c 100 -n 50000 "http://localhost:8000/hello"

2.gunicorn 性能测试
执行test.py，运行命令如下：
gunicorn -w 2 test:app
运行结果:
ab -c 100 -n 50000 "http://localhost:8000/hello"

性能总结：
方案并发最大响应时间（ms）1.uwsgi15206192.gunicorn566836总体来看，uwsgi 性能要强于 gunicorn 几倍多~
优缺点对比：
gunicorn 相对简单
uwsgi 相对复杂些，繁琐些。但性能更强悍~
部署方案：
uwsgi +nginx （个人使用推荐）
gunicorn + nginx
扩展：知识
nginx 相对 apache 的优点：
轻量级，同样起web 服务，比apache 占用更少的内存及资源抗并发，nginx 处理请求是异步非阻塞的，而apache 则是阻塞型的，在高并发下nginx 能保持低资源低消耗高性能高度模块化的设计，编写模块相对简单社区活跃，各种高性能模块出品迅速啊
