why livewire is too show

I am using the 'Create a Livewire Counter Component' example from the Livewire 3 documentation.

I am new to Livewire and don't understand why it takes 1.5 seconds to update the number when incrementing or decrementing. I'm running this on localhost. Is because of server call

php artisan make:livewire counter

 
namespace App\Livewire;
 
use Livewire\Component;
 
class Counter extends Component
{
    public $count = 1;
 
    public function increment()
    {
        $this->count++;
    }
 
    public function decrement()
    {
        $this->count--;
    }
 
    public function render()
    {
        return view('livewire.counter');
    }
}

<div>
    <h1>{{ $count }}</h1>
 
    <button wire:click="increment">+</button>
 
    <button wire:click="decrement">-</button>
</div>
