### Answer --- Here are some steps to troubleshoot and reduce latency in your Conversation Flow agent: ## Check Your Latency Metrics You can monitor latency of individual calls in the "Call History" section of your dashboard. [(1) ]() Key metrics to review: - **P90 (90th Percentile) **: 90% of calls have latency below this value - **Median (50th Percentile) **: Half of calls have latency less than this value - **End-to-End Latency**: Total time from when the user stops speaking until the AI begins responding Production voice AI agents typically aim for 800ms or lower latency to maintain conversational flow. [(2) ]() ## Optimization Recommendations **Change to a Faster LLM**: Use a more efficient language model to reduce response time. [(3) ]() **Change to a Faster TTS**: Implement a faster text-to-speech system for quicker audio output. ## Conversation Flow-Specific Considerations - Large prompts and many transitions in a node can add latency [(4) ]() - Complex tool coordination or multiple decision branches may impact performance [(5) ]() - Review your node transitions and ensure proper configuration ## Possible Platform Issues Community reports indicate there have been temporary infrastructure issues causing high E2E latency that were resolved by Retell's team (such as GPU provider issues) . [(4) ]() [(6) ]() If your agent was working fine previousl

y without any changes on your end, it may be worth checking [Retell's status page]() or reaching out to support. Would you like me to provide more details on any of these optimization approaches?
