Hello Antonis,
We apologize for the inconvenience. We have conducted another test of your site on GTMetrix and the results are still not satisfactory: https://gtmetrix.com/reports/demo01.coreit.gr/Kq6LypKz/.
There are several steps you can take to improve the speed of your WordPress website based on the GTMetrix suggestions:
1. Reduce initial server response time:
Optimize your server configuration and hardware, or consider upgrading to a faster server.
Minimize the number of plugins and scripts running on your site, and remove any unnecessary ones.
Use caching plugins like WP Rocket to reduce the server load and speed up the response time.
2. Avoid an excessive DOM size:
Minimize the number of requests your site makes to the server by reducing the number of scripts and plugins.
Defer loading of JavaScript and CSS files using plugins like Async JavaScript or WP Deferred JavaScripts.
Use lazy loading of images to reduce the initial page size.
3. Avoid chaining critical requests:
Minimize the number of requests made by critical resources like CSS and JavaScript files.
Use minification and compression of CSS and JavaScript files, we have a CSS minification option under Theme Options >> Speed Optimization.
Load essential resources inline and defer non-essential ones.
4. Use a Content Delivery Network (CDN):
Use a CDN to serve your site’s static assets from multiple server locations to reduce the load time for users in different locations.
5. Serve static assets with an efficient cache policy:
Set the cache control headers on your static assets like images, CSS, and JavaScript files to enable browser caching.
Use a caching plugin like WP Rocket to enable server-side caching and improve the load time of your site.
By implementing these steps, you should be able to improve the speed of your WordPress website and achieve a better score on GTMetrix.
We hope this issue can be resolved soon.
Best regards, 8Theme’s Team
