Sprint circuits are the way to increase speed if your knees are up to the challenge. At 2/3rds of a mile, you can inject 4 sprint circuits about every 880 ft. Run normally for those 800 ft and sprint the 80 ft as fast as you can. Regulate your breathing during this whole exercise to prevent yourself from feeling like death. You'll still be tried, but less liable to vomit everywhere.Laps. I do 2/3 a mile every other day and it takes me a ridiculously long time (around 50 minutes). I want to get a mile a day, then increase speed until I can do it in thirty minutes.
Jogging is good for keeping pace for distance, think of this as baseline. As you increase your sprint distance your baseline jog will become faster and thus carry you further.
Sprinting also helps open the stride which is another reason why people can have slow mile times. Longer strides mean less work spent shuffling your legs and more distance covered in less time.
A sprint circuit - jog - sprint circuit cardio plan with rest days will get you running miles much faster. Don't neglect the rest days, especially if weight is a concern for your knees. Better to let yourself heal today instead of buying a one-way ticket to Snap City tomorrow.
Edit: I'm retarded and thought you were talking about running laps, not swimming. My advice still stands for land-based cardio but I can't help you with swimming.
