Performance Optimizer Skill

Use this skill when the user reports “slow pages” or asks to “optimize” code.

Checklist

1. Database (The Usual Suspect)

• N+1 Detection: Look for loops calling relationships.
  • Bad: @foreach ($users as $user) {{ $user->posts->count() }} @endforeach
  • Fix: User::withCount('posts')->get()
• Indexes: Ensure searching columns (slugs, foreign keys, status) are indexed.

2. Livewire / Filament

• Computed Properties: Use #[Computed] for expensive calculations that don’t need to run on every dehydrate.
• Lazy Loading: Use lazy() on heavy components.

#[Computed]
public function heavyData()
{
    return ...;
}

3. Caching

• Cache Facade: Cache::remember('key', 60, fn() => ...) for unrelated data.
• Model Caching: If generic, use the model’s booted method to clear cache on updates.

4. Cloudflare / HTTP

• Check headers for Cache-Control.
