Hi @oclenxaodua! 👋

255ms ping to api.githubcopilot.com is actually pretty good, so this is likely not a network issue on your end. Let's troubleshoot this:

🔍 Quick Checks:

1. Check GitHub Copilot Status first:

   • Visit: https://www.githubstatus.com/
   • Look for any incidents related to "Copilot" services
   • There may be ongoing performance degradation

2. Check which model you're using:

   • VS 2022: Tools → Options → GitHub Copilot
   • If you're using Claude 3.5 Sonnet or GPT-4, those can be slower than the default models
   • Try switching to GPT-3.5-turbo temporarily to see if speed improves

🛠️ Troubleshooting Steps:

1. Clear Copilot Cache:

   Close VS 2022
   Delete: %LOCALAPPDATA%\GitHub Copilot\Cache
   Restart VS 2022
   

2. Check VS Extension:

   • Extensions → Manage Extensions
   • Update "GitHub Copilot" to the latest version
   • Current latest is v1.205.0.0 (Oct 2025)

3. Check your subscription status:

   • Go to https://github.com/settings/copilot
   • Ensure your Copilot subscription is active and not rate-limited

4. Try VS Code as a test:

   • Install VS Code + Copilot extension temporarily
   • Test if the slowness persists
   • If VS Code is fast but VS 2022 is slow, the issue is VS-specific

📊 Performance Metrics:

What's "slow" for you?

• Normal: 1-3 seconds for simple completions
• Slow: 5-10 seconds
• Very slow: 10+ seconds

💡 Workaround for Now:

If this is server-side degradation:

• Use inline completions instead of chat for now (they're usually faster)
• Reduce context by working in smaller files
• Consider temporarily switching to GitHub Copilot Free tier if you're on Business (different server pools)

Can you share:

1. Exact VS 2022 version? (Help → About)
2. Copilot extension version?
3. How long does a typical completion take?

This will help narrow down if it's a VS 2022-specific issue or server-side! 🚀

I've seen occasional slow responses too, though it's not all the time. A ping of about 255 ms is a little high, but if your connection is steady and you're not losing packets, that by itself shouldn't usually make Copilot Chat feel super slow. It might be due to temporary server issues or a problem in your area. You might also want to see if the slowdown happens with all prompts or just longer ones, and if it's the same for code suggestions and Copilot Chat. I hope the GitHub team can check it out and see if there are any performance problems. Thanks for letting us know.
