Lately I have been more active with my projects, which also meant more active on my website(s). This is when I discovered that they were not responsive. At all. Sure, on average the load time of a page was around a second, which is quite acceptable once you get used to it. But on some days I was waiting for more than 5 seconds for a page to load, with peaks of 10 seconds.
Of course, this was unacceptable. And I started searching for solutions. Luckily, WordPress is a widely used CMS, and problems like these are already solved by other users..
Besides the technical improvements like adding caching, reducing image sizes, compressing files etc, I also decided to move to a different hosting company.
I can hardly believe how much of a difference all those changes have made. Pages load almost instantaneously now. Feel free to try it yourself ;)
