⚡ Best Practices for Production

Expected Performance in Production

1 LiteLLM Uvicorn Worker on Kubernetes

Description	Value
Avg latency	50ms
Median latency	51ms
/chat/completions Requests/second	35
/chat/completions Requests/minute	2100
/chat/completions Requests/hour	126K

1. Switch of Debug Logging

Remove set_verbose: True from your config.yaml

litellm_settings:
  set_verbose: True

You should only see the following level of details in logs on the proxy server

# INFO:     192.168.2.205:11774 - "POST /chat/completions HTTP/1.1" 200 OK
# INFO:     192.168.2.205:34717 - "POST /chat/completions HTTP/1.1" 200 OK
# INFO:     192.168.2.205:29734 - "POST /chat/completions HTTP/1.1" 200 OK

2. On Kubernetes - Use 1 Uvicorn worker [Suggested CMD]

Use this Docker CMD. This will start the proxy with 1 Uvicorn Async Worker

(Ensure that you're not setting run_gunicorn or num_workers in the CMD).

CMD ["--port", "4000", "--config", "./proxy_server_config.yaml"]

3. Switch off spend logging and resetting budgets

Add this to your config.yaml. (Only spend per Key, User and Team will be tracked - spend per API Call will not be written to the LiteLLM Database)

general_settings:
  disable_spend_logs: true
  disable_reset_budget: true
