How long does it take to do a dungeon in vanilla

Before I started playing on Kronos I had no idea how long a dungeon run would take on this kind of vanilla private server. I wanted to know but I couldn't find the information, so here it is for you!

(The time it takes to make the group is not included, this depends on the server.)
