How do I improve the loading speed of my site?
In a nutshell: Few to no apps. Use premium theme. Optimise images, remove / outsource unused code.
A cookie banner alone slows down the speed immensely. Meanwhile, the real speed of the website is more important. There is still a person sitting at the end device. However, if the page takes 2.5 seconds or more to load, we have a lot of problems.
