I have a preset for the most basic things that saves me a minute or so. It includes denoising, sharpening and some saturation correction. It works for low iso values up to 400, for higher values I adapt the parameters manually, but I think one day I will do a high iso preset as well.
In general the time for one picture is somewhere between one minute and several hours. It depends on the image. Check the videos from Harry Durgin (https://m.youtube.com/user/harrydurgin) and your 10 minutes will feel ultrafast 
.
Furthermore, if you have several images in similar light, you could copy one edit to the remaining pictures, which I use a lot as well.
Edit: And I must admit that I have a backlog of several 100 if not 1000 unprocessed images 
.
