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 -c 100 -r 100 -b http://127.0.0.1:5000/

django测试结果为:

Transactions:       10000 hitsAvailability:      100.00 %Elapsed time:       18.51 secsData transferred:        0.02 MBResponse time:        0.18 secsTransaction rate:      540.25 trans/secThroughput:        0.00 MB/secConcurrency:       99.35Successful transactions:       10000Failed transactions:           0Longest transaction:        0.30Shortest transaction:        0.12

django(去掉所有middleware)测试结果为:

Transactions:       10000 hitsAvailability:      100.00 %Elapsed time:       12.97 secsData transferred:        0.02 MBResponse time:        0.13 secsTransaction rate:      771.01 trans/secThroughput:        0.00 MB/secConcurrency:       99.41Successful transactions:       10000Failed transactions:           0Longest transaction:        0.28Shortest transaction:        0.12

flask测试结果为:

Transactions:       10000 hitsAvailability:      100.00 %Elapsed time:        5.47 secsData transferred:        0.02 MBResponse time:        0.05 secsTransaction rate:     1828.15 trans/secThroughput:        0.00 MB/secConcurrency:       96.25Successful transactions:       10000Failed transactions:           0Longest transaction:        0.11Shortest transaction:        0.00

bottle测试结果为:

Transactions:       10000 hitsAvailability:      100.00 %Elapsed time:        4.55 secsData transferred:        0.02 MBResponse time:        0.04 secsTransaction rate:     2197.80 trans/secThroughput:        0.00 MB/secConcurrency:       96.81Successful transactions:       10000Failed transactions:           0Longest transaction:        0.09Shortest transaction:        0.00

tornado测试结果为:

Transactions:       10000 hitsAvailability:      100.00 %Elapsed time:        7.06 secsData transferred:        0.02 MBResponse time:        0.07 secsTransaction rate:     1416.43 trans/secThroughput:        0.00 MB/secConcurrency:       99.51Successful transactions:       10000Failed transactions:           0Longest transaction:        0.09Shortest 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。
