Performance Optimization

<script setup>
// Async component loading
const HeavyComponent = defineAsyncComponent({
  loader: () => import('./HeavyComponent.vue'),
  loadingComponent: LoadingSpinner,
  errorComponent: ErrorComponent,
  delay: 200,
  timeout: 3000
})

// Keep-alive for component caching
</script>

<template>
  <KeepAlive :max="10" :include="['ComponentA', 'ComponentB']">
    <component :is="currentComponent" />
  </KeepAlive>
</template>

<!-- v-memo for expensive lists -->
<template>
  <div v-for="item in list" :key="item.id" v-memo="[item.id, item.updated]">
    <!-- Expensive rendering -->
  </div>
</template>
