We have just completed updating all of our resources on Kloodle so that they are now loaded using AJAX. This has improved performance exponentially. Previously, we have had issues with loading profiles that contain a lot of content. Data was loaded all at once, leading to long loading times, especially during lessons at schools and colleges on slower connections. AJAX loading has improved this.
We have also added caching to the site, which has again contributed to faster loading times. We will continue to tweak the infrastructure of the site to improve performance and speed.
