# Obsidian Performance Tuning ## Overview Optimize Obsidian plugin performance for large vaults (10,000+ files): profile bottlenecks with DevTools, implement lazy initialization, process files in batches with UI yielding, use LRU caches with bounded memory, debounce event handlers, and optimize DOM rendering with virtual scrolling and DocumentFragment. ## Prerequisites - Working Obsidian plugin with at least one performance concern - Developer Console access (Ctrl+Shift+I / Cmd+Option+I) - Understanding of async JavaScript and the event loop ## Performance Benchmarks | Metric | Good | Warning | Critical | |--------|------|---------|----------| | Plugin load time (`onload`) | < 100ms | 100-500ms | > 500ms | | Command execution | < 50ms | 50-200ms | > 200ms | | Single file operation | < 10ms | 10-50ms | > 50ms | | Memory increase on load | < 10MB | 10-50MB | > 50MB | | Event handler execution | < 5ms | 5-20ms | > 20ms | ## Instructions ### Step 1: Profile with DevTools Performance Tab ```typescript // Add timing instrumentation to identify bottlenecks export default class MyPlugin extends Plugin { async onload() { const loadStart = performance.now(); await this.loadSettings(); console.log(`[perf] loadSettings: ${(performance.now() - loadStart).toFixed(1)}ms`); const indexStart = performance.now(); await this.buildIndex(); console.log(`[perf] buildIndex: ${(performance.now() - indexStart).toFixed(1)}ms`); const cmdStart = performance.now();...
