Bits about Django performance, scalability and deployment
Keep the upper hand in Django deployment.
Set up a complete Django production server using just one console command (nginx+gunicorn under supervisord, PostgreSQL).
Deployment with complete versioning and quick rollback to any of the previous versions. Different settings for different server groups (with setup, pre- and post deployment scripts).
Deploying Django and gunicorn with multiple workers on a single free Heroku node.
Combined with an external PostgreSQL instance coupled with connection pooling, it gives a massive 8x speedup.
Improve your Django and PostgreSQL application performance by using connection pooling. No coding and virtually no effort required for 2 times better response times.

My method works even with SendGrid.
