Yes, Dailymotion like most smaller video sites suffer from slowdowns since I think a lot of people use them, but they can't afford better web hosting and website software like YouTube which is owned by Google, so it's fastest usually.
Indeed, but Dailymotion.com gets a lot of traffic. It is one of the top 100 most visited sites in the world according to Alexa.com. Getting a faster server might cost a lot more.
I feel if they got rid of all their sexy videos , their site might be a lot faster since most of their most viewed videos have nudity in it. But, a lot fewer people visit their site.
