  1. DjangoToolbar
    • reduce queries
  2. Monitor
    • move database to separate server
  3. Memcached
    • doesn't increase speed (doesn't work, timestamp debugging)
    • due to cookies
    • don't delete cookies
  4. Development machines to get cookies and caching running
  5. OperationalErrors
    • maximum connections to postgres
    • enter pgbouncer to re-use connections
  6. Long communication
    • async workers: celery + redis
