Nginx upload module vs Flask

Env

Ubuntu 12.04 32bit

Nginx 1.1.19 (HTTP server)

Flask 0.9 (light python framework)

Gevent: 1.0rc2 (coroutine I/O)

Gunicorn 0.17.2 (WSGI server)

Nginx setting

Nginx listen to port 8666

serves requests to URL /upload

and also work as a reverse proxy to Flask which serve requests on port 8222

Server code

server application run in 5 worker mode with Gunicorn + Gevent

gunicorn -k gevent -b 0.0.0.0:8222 -w 5 t:app

Test code

start N threads, and upload file to the URL

Result

Performance test result:

Unit: seconds

file size: 3.3 MB

concurrent number	Flask 0.9 + gevent 1.0rc2 + gunicorn 0.17.2 + Nginx (5 worker processes)	Nginx + Nginx upload module
50	6.029	2.328
100	12.788	4.995
200	28.828	10.813

As we expected, Nginx upload module which written in C, is about twice faster than pure python code while processing file uploading.
