# Troubleshoot High Latency

> Steps to diagnose and fix end-to-end latency issues exceeding 3 seconds.

If your end-to-end latency P90 exceeds **3 seconds**, follow these steps.

<Steps>
  <Step title="Check estimated latency">
    * Look for features marked with a **turtle icon** in your agent configuration
    * If estimated latency exceeds 1.5s, disable some of those features to reduce it
  </Step>

  <Step title="Monitor LLM response time">
    Check your LLM latency. Normal range: **500ms–900ms**.

    If consistently above 900ms:

    * Switch to the fast tier
    * Switch to an alternative LLM provider
    * Or wait for your current provider to resolve performance issues
  </Step>

  <Step title="Check the status page">
    Check the UponAI Status Page for any ongoing incidents. Wait for active issues to resolve before further troubleshooting.
  </Step>

  <Step title="Consider geographic distance">
    International calls introduce additional latency due to geographic distance:

    * Check if you're calling across countries or continents
    * Use a phone number geographically closer to your target audience
  </Step>

  <Step title="Contact support">
    If the above steps don't resolve the issue, contact support with:

    * Your **Call ID**
    * Steps already tried
    * Current latency measurements
  </Step>
