Filament v4, officially released on August 12, 2025, brings significant performance improvements over the previous version (v3). Based on official testing and documentation, Filament v4 offers rendering speeds up to 2-3x faster, especially for tables and forms. New features such as partial rendering and blade template optimization make our Laravel applications more responsive, especially when handling large datasets.

Performance is Key in Filament V4

Filament is designed to help Laravel Developers create more efficient and practical admin panels. In the previous version, version 3, rendering tables with large datasets felt very slow. Filament v4 addresses this with deep optimization, from the server side to the client-side. The result? Applications with faster performance, lower memory consumption, and a smoother user experience.

Key Features of Filament v4 to Improve Performance

Filament v4 focuses on reducing rendering overhead and server requests. Here are some features along with how they work and examples of implementation:

1. Optimization of Blade Templates and Table Rendering

Many Blade templates have been optimized to reduce the number of views rendered. Instead of loading new files, Filament v4 uses existing PHP objects to generate HTML. Additionally, Tailwind CSS group classes are extracted into dedicated classes, reducing HTML size and accelerating page loading. One feature we will discuss is the lazy() method on table components. Open your resource file in the app/Filament/Resources/**/*.php directory, then paste the lazy() method into the table component like this.

public static function table(Table $table): Table
{
    return $table
        ->recordTitleAttribute('name')
        ->columns([
            TextColumn::make('name')->sortable(),
            TextColumn::make('price')->money('usd'),
        ])
        ->lazy();
}

However, when installing resources, if you choose separate configurations, you need to open the table configuration file located in the directory app/Filament/Resources/**/Tables/*.php.

2. Partial Rendering for Forms and Components

This feature allows only specific parts of a form to be re-rendered after a state update, rather than the entire page. Methods such as partiallyRenderComponentsAfterStateUpdated() or skipRenderAfterStateUpdated() help save server time. This makes form interactions faster and ideal for applications with dynamic fields.

TextInput::make(‘name’)
    ->live()
      ->partiallyRenderComponentsAfterStateUpdated([‘email’])
    
TextInput::make(‘email’)
    ->label(fn (Get $get): string => filled($get(‘name’)) ? “Email address for {$get(‘name’)}” : ‘Email address’)

3. JavaScript Hooks

There are methods such as hiddenJs(), visibleJs(), and afterStateUpdatedJs() that will execute logic in the browser without requesting the server and can reduce latency.

TextInput::make(‘discount’)
    ->hiddenJs(‘state.quantity < 10’) // hide if qty < 10
    ->afterStateUpdatedJs(‘alert(“Discount updated!”)’);

4. Improved Bulk Actions for Large Datasets

The chunkSelectedRecords() method processes records in small batches and reduces memory usage. Prebuilt bulk actions no longer hydrate all models, and tracking deselected records optimizes the “Select all” action.

// Force Delete Action
ForceDeleteBulkAction::make()->chunkSelectedRecords(250)

// Delete Action
DeleteBulkAction::make()->chunkSelectedRecords(250)

// Restore Action
RestoreBulkAction::make()->chunkSelectedRecords(250)

5. Efficient Icons with Heroicon ENUM

In Filament v3, icons are managed as strings, which can cause errors and slow down rendering. However, this is not the case in Filament v4, which uses enums for icons, improving type safety and icon rendering efficiency.

//Icon Navigation
protected static string|BackedEnum|null $navigationIcon = Heroicon::OutlinedStar;

// Icon Input
TextColumn::make(‘status’)
    ->icon(HeroIcon::STAR);

6. Improved Global Search Performance

By default, global search in Filament breaks search queries into separate words and searches for each word independently, allowing for more flexible search results. However, this approach can slow down performance when handling large datasets due to increased query complexity. In Filament v4, there is a new property $shouldSplitGlobalSearchTerms that allows developers to disable word splitting in global searches and reduce query complexity on large datasets.

protected static ?bool $shouldSplitGlobalSearchTerms = false; //set false

7. Caching Components (PRODUCTION)

The command php artisan filament:cache-components creates a cache for component indexes (resources, pages, widgets), reducing auto-discovery time, which is very helpful for applications with many components. Alternatively, use php artisan optimize for comprehensive optimization, including component caching.

Conclusion

Filament v4 is a must-have upgrade for Laravel developers aiming for high-performance applications. Features like partial rendering, JS hooks, and bulk action optimization can reduce rendering time by 2-3x while keeping the code clean and simple.
