There are three issues with YouTube: 1. Slow website performance - for example, clicking on a video to pause/start it takes a few seconds to complete. Writing comments - after pressing a key, a second passes before the letter appears. Refreshing the page is also delayed. 2. Very often, the video starts at the lowest resolution, despite being connected to a 1Gb fiber optic cable. 3. Extremely high memory usage compared to Chrome.
