Optimizing Django and Celery for Handling Many Concurrent Requests

Handling a high volume of concurrent requests in a Django application with Celery for background tasks can be challenging. This guide will walk you through the necessary steps to optimize your setup for better performance and scalability.

Default Setup with Gunicorn and Celery

By default, Gunicorn with Django and Celery uses synchronous workers to handle web requests and background tasks. This means:

• Gunicorn: Uses sync workers which can handle one request at a time per worker.
• Celery: Processes tasks synchronously within each worker.

1. Edit the file at /Library/Backblaze.bzpkg/bzdata/bzexcluderules_editable.xml.
2. Add these rules inside the bzexclusions tag:

<!-- Exclude node_modules. -->
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/node_modules/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/.git/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

This will enable Sass+Compass with LiveReload through Guard. (Guard screen cast)

You will also need a browser component to communicate with LiveReload. (browser extension, livereload.js)

If you prefer going through a GUI, that option is available. The following instructions is specific to Mac OS X and it works through the command line.

Note that this is not specific to Rails projects. This can work for any standalone front-end project.
