Cursor Performance Tuning

Diagnose and fix Cursor IDE performance issues. Covers editor optimization, indexing tuning, extension auditing, AI feature configuration, and strategies for large codebases.

Performance Diagnostic Workflow

Step 1: Identify bottleneck
         ├── Editor lag? → Step 2 (Editor settings)
         ├── High CPU?   → Step 3 (Extension audit)
         ├── Slow AI?    → Step 4 (AI tuning)
         └── Memory?     → Step 5 (Memory management)

Step 2: Editor settings
         ├── Disable minimap, breadcrumbs
         ├── Reduce file watcher scope
         └── Increase memory limits

Step 3: Extension audit
         ├── Profile running extensions
         ├── Disable heavy extensions
         └── Use workspace-scoped disabling

Step 4: AI feature tuning
         ├── Optimize .cursorignore
         ├── Use faster models
         └── Manage chat history

Step 5: Memory management
         ├── Close unused workspace folders
         ├── Limit open editor tabs
         └── Clear caches
