Snuggli Performance Audit Report

January 12, 2026 • Comprehensive System Analysis

Overall Performance Score

4.5/10

Needs Immediate Attention

Target: 9+/10

Executive Summary

The Snuggli system is functional but suffers from critical performance issues:

  • Over-aggressive caching to avoid rate limits has created stale data and memory leaks
  • Admin dashboard fetches 10,000+ records without pagination
  • TalkToAraba is 1,288 lines in one file
  • No code splitting results in massive initial bundle
  • Memory usage grows unbounded due to infinite garbage collection timers

With fixes: 3-5x faster load times, 70% memory reduction, Lighthouse >90

Critical Issues

React Query Config

2/10

Problem: staleTime: Infinity and gcTime: Infinity everywhere causing stale data and memory leaks

Impact: Users see outdated data, browser tabs crash after prolonged use

Fix: Balanced caching with smart invalidation

TalkToAraba Component

3/10

Problem: 1,288 lines in single file, 20+ useState, dozens of useEffects

Impact: Slow load, difficult maintenance, unnecessary re-renders

Fix: Split into 10+ focused components, extract hooks, use React.memo

Admin Dashboard

2/10

Problem: Fetching 10,000+ records client-side, no pagination, client-side aggregation

Impact: 30-60s load times, memory exhaustion, crashes

Fix: Server-side aggregation API, pagination, proper caching

Code Splitting

1/10

Problem: No React.lazy() for routes, massive upfront bundle

Impact: Slow First Contentful Paint, poor Lighthouse scores

Fix: Route-based code splitting with React.lazy()

Memory Management

3/10

Problem: gcTime: Infinity everywhere, queries never garbage collected

Impact: Unbounded memory growth, tab crashes

Fix: Set reasonable GC timers (30-60 min)

Component Optimization

4/10

Problem: No React.memo on expensive components, missing useMemo/useCallback

Impact: Unnecessary re-renders, wasted computation

Fix: React.memo key components, optimize hooks

List Virtualization

3/10

Problem: Rendering 1000+ items without virtualization

Impact: Slow scrolling, high memory usage

Fix: Implement react-virtual for long lists

Database Queries

5/10

Problem: Client-side filtering, no pagination, N+1 patterns

Impact: Excessive data transfer, slow queries

Fix: Server-side aggregation, cursor pagination

Performance Targets

Week 3: Medium Priority

  • •List virtualization
  • •Image optimization
  • •Bundle size reduction

Week 4: Polish

  • •Performance monitoring
  • •Final optimizations
  • •Load testing

Expected Outcomes
