Equal starting conditions for the providers
The WordPress website for the test was 350MB – complete with images, plugins, a blog and 2 other custom post types (FAQ and projects). I did not use a CDN for the tests.
On each server, I first optimized the WordPress website with a focus on Google PageSpeed. Raidboxes and Kinsta do not support WP Super Cache, for example. Likewise, .htaccess settings are of no use, since Nginx is used as the operating system.
With ALL-INKL and Hetzner, on the other hand, the full program was possible before the test could begin. I set up WP Super Cache, Automize, Perfmatters as optimization plugins and also extensively edited the .htaccess file.
SSL was enabled in all tests.
