Page is re-rendering on client side causing slow page speed

HI,
we have noticed that pages that are coming to form builder.io are loading much longer than if we put static HTML. Also, the page seams to re-render on the client side.

Here is the Link to the Page: R Big Bags Abholung / Entsorgung beauftragen – Berlin Recycling Shop

What are you trying to accomplish
The Page is re-rendering on the clientside causing a page speed increase.

Code stack you are integrating Builder with
NextJS

Reproducible code example

import { builder } from '@builder.io/sdk';
import { notFound } from 'next/navigation';

import { builderInit } from '@/lib/builder-io/builder-init';
import { RenderBuilderContent } from '@/lib/builder-io/render-builder-content';

// Initialize Builder.io
builderInit();

interface PageProps {
  params: {
    path?: string[];
  };
}

export default async function Page({ params }: PageProps) {
  if (!params?.path?.length) return notFound();

  const urlPath = `/pages/${params.path.join('/')}`;

  try {
    const builderPage = await builder
      .get('page', {
        options: { includeRefs: true, noTraverse: false },
        userAttributes: { urlPath },
        prerender: false,
        cachebust: false,
        cache: true
      })
      .toPromise();

    if (builderPage) {
      return <RenderBuilderContent model="page" content={builderPage} />;
    }

    return notFound();
  } catch (error) {
    console.error('Error fetching Builder.io content:', error);
    return notFound();
  }
}

We also wrap our content in a custom component called global-container. Maybe the custom component is the problem…
