$ claude-trace!The Problem
Claude Code takes a long time to respond to prompts, with noticeable delays between sending a message and receiving a response.
?Common Causes
- •Network latency to Anthropic's API servers
- •Large context from long conversation history
- •Many files being analyzed or included
- •Local resource contention from other Claude sessions
- •System memory pressure causing swap usage
- •Rate limiting from API
🔍How to Diagnose
First, rule out local resource issues: ```bash # Check if Claude is CPU or memory bound locally claude-trace -v # Look at system-wide pressure memory_pressure ``` If local resources look fine, the issue is likely network or API-related.
✓Solution
1. **Reduce local resource contention**: - Kill unused Claude sessions with Claude Trace - Close other heavy applications 2. **Reduce context size**: - Start a new conversation - Use more focused prompts - Reference specific files instead of entire directories 3. **Check your connection**: - Try a different network - Check Anthropic status page 4. **Optimize file includes**: - Use `.claudeignore` to exclude unnecessary files - Be specific about which files to analyze
🛡Prevention
- Keep conversation contexts focused and restart when they get long - Maintain a `.claudeignore` file in all projects - Use Claude Trace to ensure you're not running excessive sessions - Close Claude sessions you're not actively using
