Perf Profiler

Profile and optimize application performance — detect N+1 queries, memory leaks, slow renders, and bundle bloat with actionable fix recommendations.

Features

• N+1 Query Detection — Identifies database query patterns that cause performance degradation at scale
• Bundle Analysis — Visualizes JavaScript bundle composition and flags oversized dependencies
• Render Profiling — Detects unnecessary re-renders, expensive computations, and layout thrashing
• Memory Leak Detection — Tracks heap growth patterns and identifies objects that resist garbage collection
• Performance Budget — Sets and enforces budgets for load time, bundle size, and API response latency

Quick Start

claude skill install perf-profiler

Usage

# Profile the application and generate a performance report
/perf-profiler analyze

# Check bundle size against performance budget
/perf-profiler bundle --budget 200kb

How It Works

Analyzes your codebase statically for known performance anti-patterns: nested loops over data, missing database indexes, unoptimized images, and synchronous operations that should be async. For runtime profiling, instruments your application to capture timing data, memory snapshots, and network waterfalls. Produces a prioritized list of optimizations with estimated impact scores.

Compatibility

Works with Claude Code, Codex, Gemini CLI, Cursor, Windsurf, and Aider.
