Django + Raspberry PI

[Nicolas Emiliani]

Hey guys!

Has anyone tried to run django + sqlite on a raspberry pi ? Any performance issues ?

I'm about to start an app that provides a restful api and has to run on RPI, it's going

to manage an automation service, so load is going to be pretty low.

Cheers.

Yep, I got my full development environment for one of my company's
applications running on it with almost no problem. The one exception
was MongoDB, which is for x86 only, so I had to compile a fork, which
took about 10 hours on the Pi.

It was definitely pretty slow, but it works.

Our stack includes nginx, gunicorn, Redis, MongoDB, PostgreSQL,
supervisor, virtualenv, and probably other stuff I'm forgetting.

It is a computer, after all. Just slow, not too much RAM, and with an
ARM processor.

Shawn,

Well you are running a pretty interesting and (heavy?) stack, I've read about DB engines being slow. Thanks for the data.

With an intro sentence like that and the lilliputian dimensions of the
RPI, I half expected you to say that you ran it *on the pinewood
derby race car itself*. :-)

Slow ARM processor.

Did you try to cross compile mongodb or use qemu chroot/proot ?

Here is an explaination on how to cross build a gentoo from another gentoo and and an environnement setup to do be able to qemu proot and compile anything (as if it was compiled on the raspberry)... I divides by 6 the time needed to compile raspberry pi kernel with modules (less than 1hour) and you get all the benefit of a source distribution :)

If you don't use a gentoo you can setup portage prefix or chroot.

OR

you can use distcc with a cross compiler.

HTH,

Amirouche

This will be a long way home for you I recommend you setup a cross compiler and use distcc

The RPi board would fit on a car, but you would have to remove the hdmi and power connectors to keep from being too wide. However I am considering mounting an arduino with flashing leds for my granddaughter's car next year. (Off topic apology)

A bit dated, but since this page came up when I ran into the same issue, thought I'd post my fix.

Pretty much I turned off DEBUG in the settings.py file, and the performance is fine now = )

Best Wishes,
