Run django application on apache with uWSGI

Question

I wanted to run my django application using apache and uWSGI. So I installed apache which use worker_module. When I finally run my app and tested its performance using httperf I noticed that system is able to serve only one user at the same time. The strange thing is that when I run uWSGI using the same command as below with nginx I can serve 97 concurrent users. Is it possible that apache works so slow?

My apache configuration looks like (most important elements - the extant settings are default):

<IfModule mpm_worker_module>
    StartServers          2
    MinSpareThreads      25
    MaxSpareThreads      75
    ThreadsPerChild      25
    MaxClients           63
    MaxRequestsPerChild   0
</IfModule>
...
<Location />
    SetHandler uwsgi-handler
    uWSGISocket 127.0.0.1:8000
</Location>

I run uwsgi using:

uwsgi --socket :8000 --chmod-socket --module wsgi_app --pythonpath /home/user/directory/uwsgi -p 6

I recommend that you put Apache behind Nginx. For example:

• bind Apache to 127.0.0.1:81
• bind nginx to 0.0.0.0:80
• make nginx proxy domains that Apache should serve

It's not a direct answer to your question but that's IMHO the best solution:

• best performance
• best protection for Apache
• allows to migrate Apache websites to Nginx step by step (uWSGI supports PHP now ...), again for best performance and security
