The Old (Slow) Way
Traditional content management systems (CMSs) like Wordpress or Squarespace are notoriously slow. They require you to manage multiple plugins, install security updates, troubleshoot custom code and pay ongoing hosting or subscription fees. And after all of that they still perform poorly. There is a better way.
The New (Fast) Way
Modern websites are built using JAMstack architecture. They load incredibly fast even with multiple large image galleries. There are no hassles with security or plugins breaking and you can say goodbye to ongoing monthly fees because hosting is free.
