Trying jinja2 in your project is hard - you are using some template
tags, and you would need to port them to jinja2. Then you would need
to rewrite your templates so that they work unde

Hi,
I am interessted in the result. Please post
I recommend you give this a shot:
http://backslashn.com/post/505601626/profiling-execution-with-the-django-debug-toolbar
It might give some clues and is VERY fast to setup.

Good catch.
Drakkan, I suggest trying out this ProfilingPanel for the Django Debug
Toolbar (very easy to setup).

I'd be very curious to know what you find.

The best way to check where your performance problems come from is
using profiling.

Pretty interesting..
So, I've an idea here..
Why don't you log this output in some file.. (and share)
def page (request):
start = time.time()
# function definition
elapsed = (time.time() - start)
return HttpResponse()
This way, see if its the framework that's taking the time, or its

Hi,
Have you tried any kind of DB connection pooling with Django?
I find Jacob's Deployment Workshop [0] to be a treasure chest of tips
and tricks for Django deployment.
Also take a look at the code/config he uses [1].

Hi,
I would choose the framework, that you like. You can optimize later. And
this would be the same for all frameworks: You need a good cache strategy.
Are you expecting several hundred requests per minute?
I guess there is something wrong with your benchmark. I don't think

The framework might be fine (I'll give the doc a read), but the
language still sucks ;)

Hi,
Is there anyway you can upload the project to bitbucket or github ?

Hi,
thanks for your comments, I installed django-debug toolbar and I can
confirm I'm doing similar queries from both django and play. The query
I do with hibernate in play should be slower since I'm doing a left
outer join while django do an inner join, since the field on which I
join cannot be nu
We all know python is slower in raw execution speed than it's brother Java but
I can't imagine it to be _that_ slow.
Maybe there's something wrong with the queries you perform. Django's ORM is
know for it's 'hidden execution' of queries. Some more insight in your querying
code might be useful
Hi,
Install Django debug toolbar and have a look at what's wrong with your
application.
My numbers are very different from yours.
I just ran some tests and I am around 350 req/s with 4 sql queries.
I'm a on dual core (4 virtual cores), using gunicorn/mysql with debug turned

Of course Java IS faster by a few factors then Python. I switched recently
to Play development from django and I also noticed different. Moreover Play
uses many mature tools, like JPA/Hibernate, ehcache etc which are called
industrial standards.
One more thing - Play! uses its own build-in http ser

According to most benchmarks, Python (that is: current canonical

a fact. FWIW, according to the same benchmarks, Java is slower than
