python常用web框架性能测试(django,flask,bottle,tornado)

测了一下django、flask、bottle、tornado 框架本身最简单的性能。对django的性能完全无语了。

django、flask、bottle 均使用gunicorn+gevent启动，单进程，并且关闭DEBUG，请求均只返回一个字符串ok。

tornado直接自己启动，其他内容一致。

测试软件为 siege，测试os为cenos6 64位，测试命令为:

siege-c100-r100-bhttp://127.0.0.1:5000/

django测试结果为:

Transactions:               10000hits

django(去掉所有middleware)测试结果为:

bottle测试结果为:

tornado测试结果为:

Elapsed time:                7.06secs

Throughput:                0.00MB/sec
Concurrency:               99.51

Longest transaction:            0.09
Shortest transaction:            0.01

可见纯框架自身的性能为:

bottle > flask > tornado > django

结合实际使用:

• tornado 使用了异步驱动，所以在写业务代码时如果稍有同步耗时性能就会急剧下降；
• bottle需要自己实现的东西太多，加上之后不知道性能会怎样；
• flask性能稍微差点，但周边的支持已经很丰富了；
• django就不说了，性能已经没法看了，唯一的好处就是开发的架子都已经搭好，开发速度快很多

因为最近正在为一个项目选型发愁，所以就测了一下，记录在此吧。

PS: 2014-6-23 使用 centos6 64位 重新进行了测试，得出与生产环境更匹配的结果，并修改了文章。
