Website with many pages

[Carrara]

I even understand it was even a test I did.

I say this because it is a CRAWLER site, the problem would be due to every page update, it updates the sitemap.xml, the pages.xml, and the pages are not refactored at the time of listing.

I will migrate this specific site to the laravel framework ..

About migrating your website
If you want a complete CMS/CMF for your project, an intuitive back end for both end user and designer, a decoupled front end and handling thousands of pages easily I can recommend Processwire:

I'll check the documentation, thanks for the suggestion.

I've seen the panel and main page demonstration, and I'm going to study a way to deploy it.

The site I currently quoted on this topic is on the air.

The problem would be in the backend even the slowness, because the frontend is working perfectly.
