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:

代码如下:

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

django测试结果为:

代码如下:

Transactions: 10000 hits

Availability: 100.00 %

Elapsed time: 18.51 secs

Data transferred: 0.02 MB

Response time: 0.18 secs

Transaction rate: 540.25 trans/sec

Throughput: 0.00 MB/sec

Concurrency: 99.35

Successful transactions: 10000

Failed transactions: 0

Longest transaction: 0.30

Shortest transaction: 0.12

django(去掉所有middleware)测试结果为:

代码如下:

Transactions: 10000 hits

Availability: 100.00 %

Elapsed time: 12.97 secs

Data transferred: 0.02 MB

Response time: 0.13 secs

Transaction rate: 771.01 trans/sec

Throughput: 0.00 MB/sec

Concurrency: 99.41

Successful transactions: 10000

Failed transactions: 0

Longest transaction: 0.28

Shortest transaction: 0.12

flask测试结果为:

代码如下:

Transactions: 10000 hits

Availability: 100.00 %

Elapsed time: 5.47 secs

Data transferred: 0.02 MB

Response time: 0.05 secs

Transaction rate: 1828.15 trans/sec

Throughput: 0.00 MB/sec

Concurrency: 96.25

Successful transactions: 10000

Failed transactions: 0

Longest transaction: 0.11

Shortest transaction: 0.00

bottle测试结果为:

代码如下:

Transactions: 10000 hits

Availability: 100.00 %

Elapsed time: 4.55 secs

Data transferred: 0.02 MB

Response time: 0.04 secs

Transaction rate: 2197.80 trans/sec

Throughput: 0.00 MB/sec

Concurrency: 96.81

Successful transactions: 10000

Failed transactions: 0

Longest transaction: 0.09

Shortest transaction: 0.00

tornado测试结果为:

代码如下:

Transactions: 10000 hits

Availability: 100.00 %

Elapsed time: 7.06 secs

Data transferred: 0.02 MB

Response time: 0.07 secs

Transaction rate: 1416.43 trans/sec

Throughput: 0.00 MB/sec

Concurrency: 99.51

Successful transactions: 10000

Failed transactions: 0

Longest transaction: 0.09

Shortest transaction: 0.01

可见纯框架自身的性能为:

代码如下:

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。
