Anthony Trollope, back in 1883, thought 3 hours a day was more than enough time. I think most of us can only dream of having 3 hours a day to write. I'm partial to a 2 hour time slot, though I'd be more than willing to take a break then add another hour or two! How long are your writing sessions? Are you consistent with them? Do you focus on the amount of time you spend writing, or do you have to reach a certain word count before you stop?
