How do I speed up a Joomla website in 2026?

Measure field Core Web Vitals, raise PHP, enable Conservative Caching and guest Page Cache if the site allows it, compress responses, shrink the LCP image, and remove extra JavaScript. Then retest the same URLs.

What is the difference between Conservative and Progressive Caching?

Conservative caching is the safe default and respects module variation. Progressive caching stores more aggressively and is for sites that look the same to every guest. Do not use Progressive on carts, membership, or personalized modules.

Does Gzip speed up Joomla?

It reduces HTML, CSS, and JS bytes if the server was sending them raw. If Nginx already sends Brotli or Gzip, turning it on in Joomla will not magically double the gain. Check response headers.

Will a caching plugin replace a slow template?

No. Cache serves the same heavy HTML faster the second time. It does not fix a 2 MB hero or 400 KB of jQuery plugins on first view.

Is Joomla 6 faster than Joomla 3?

A current 6.x site on PHP 8.3 with Web Asset Manager is in a different league than Joomla 3 on PHP 7. The CMS version alone is not a PageSpeed plugin. You still have to size images and modules.
