Hi,
I did a small test app that basically render a web page and do 3
queries to the database (these queries are needed to fetch some data
displayed on the web page). I deployed this app with nginx+uswgi
here is the relevant nginx conf:
location / {
uwsgi_pass 127.0.0.1:49152;
include uwsgi_params;
}
I configured nginx to serve the static files too:
location /media {
root <root path for media>;
autoindex on;
}
I launch uswgi as follow:
uwsgi --chdir=<path> --
module='django.core.handlers.wsgi:WSGIHandler()' --env
DJANGO_SETTINGS_MODULE=myapp.settings --master --pidfile=/tmp/project-
master.pid --socket=127.0.0.1:49152 --max-requests=5000 --process=5
then I benchmarked the app with ab:
ab -n 1000 -c 4 http://127.0.0.1:80/
This is ApacheBench, Version 2.3 <$Revision: 655654 $>

now I implemented the same app using playframework, a java based
framework and benchmarked with ab again:
ab -n 1000 -c 4 http://127.0.0.1:9000/

so play is outperforming django! obviously django is not in debug mode
ecc..., is there something wrong in my test setup (I already tried to
adjust the uwsgi launch line I tryed more process or 1 process with
threads ecc with no relevant improvement) or django/python is simply
much slower than java? I tried to run play behind nginx proxy too: the
results are pratically identical. Note the response time too: the
slowest play response is 47 ms, the fastest django one is 110 ms,
any suggestion to improve performance is appreciated,
thanks in advance,
drakkan
