# Cursor Performance Tuning

## Overview

This skill helps optimize Cursor IDE performance. It covers performance diagnostics, editor optimization settings, extension management, AI feature tuning, and indexing configuration to ensure a fast and responsive development experience.

## Prerequisites

- Cursor IDE installed
- Access to Cursor settings
- System monitoring tools available
- Understanding of extensions and processes

## Instructions

1. Use Process Explorer to identify bottlenecks
2. Disable visual features for performance gains
3. Configure file watcher exclusions
4. Audit and disable heavy extensions
5. Optimize AI feature settings
6. Set up aggressive .cursorignore

## Output

- Improved editor performance
- Reduced CPU and memory usage
- Faster AI completions
- Optimized indexing configuration

## Error Handling

See `{baseDir}/references/errors.md` for comprehensive error handling.

## Examples

See `{baseDir}/references/examples.md` for detailed examples.

Overview

This skill helps you diagnose and optimize Cursor IDE performance to keep the editor fast and responsive. It focuses on identifying CPU/memory hotspots, tuning editor and AI settings, managing extensions, and configuring indexing and file-watch exclusions. Use it to reduce lag, lower resource use, and speed up AI completions and search.

How this skill works

The skill walks through targeted diagnostics (process and resource inspection), recommends configuration changes (editor visual features, file watcher exclusions, .cursorignore), and provides extension and AI feature tuning steps. It shows how to identify heavy processes, disable or replace costly extensions, and tighten indexing and file-watching scope to cut overhead. Final steps validate improvements using system monitoring and in-editor responsiveness checks.

When to use it

  • When Cursor IDE feels slow or unresponsive
  • After installing many extensions or large projects
  • When CPU or memory use spikes while editing
  • Before enabling resource-heavy AI features or real-time indexing
  • When seeking faster AI completions and search responsiveness

Best practices

  • Run a process-level profiler or Process Explorer to find top CPU/memory consumers before changing settings
  • Start with non-destructive changes (disable features/extensions) and measure impact
  • Exclude large folders and generated files via .cursorignore and file watcher exclusions
  • Prefer lightweight extensions or native features over multiple overlapping plugins
  • Reduce visual effects (animations, minimap) and lower editor update frequencies for big projects

Example use cases

  • Diagnose a slow Cursor session by identifying a misbehaving extension and disabling it to restore responsiveness
  • Optimize AI completion latency by reducing model polling frequency and limiting indexed scope
  • Improve startup and search speed by adding node_modules, build artifacts, and large asset folders to .cursorignore
  • Lower continuous CPU use by disabling live linting or background analysis for large repositories
  • Tune file watcher settings when working on monorepos to prevent excessive I/O

FAQ

Will these changes affect code functionality?

No. The recommendations focus on editor behavior, indexing scope, and extensions. They do not change source code. You can reverse any setting if needed.

How do I measure improvement?

Use system monitoring (CPU, memory) and time common actions (file open, search, AI completion). Compare before/after snapshots and note reduced latencies and resource use.
