Sure, you can definitely speed up cloning! However, it would really help to know exactly what method(s) you're using here?

I recently cloned for the first time using two different techniques: hormone and peat, and a homemade bubble system.

Dip-n-Grow rooting concentrate was included in my first attempt using only two cuttings, jiffy pellets, a tray, and a humidity dome under one 23 watt CFL. These did well, but took a little over ten days to root.

The process involved soaking the peat pellets in a very weak bloom fert for an hour before taking the cuttings. Then with a sharp blade (I used an exacto knife) cut at 45 degree angle and keeping in mind at least one node should be buried in the medium as this is a default spot for root growth and will speed up the overall process. Quickly dip the 45 degree end in the hormone, usually for 30 seconds or less, then place inside a jiffy/peat pellet being careful not to poke through the bottom on the medium. I read somewhere (icmag, I think) that the pre-made holes contain less oxygen in the center, so the outter edges are the place to make your hole. I just used a small nail about the size of the cutting's diameter to poke a spot for my new baby. One thing I forgot to mention, the pellets should not be soaking wet when you go to insert the cutting, but they should be a little moist.

After you've got all your future clones in the peat, place them on your tray, put the humidity dome on, and place all in a safe spot under a low-wattage CFL (or tube) about 6 to 8 inches away, as clones only need enough light to know it's day, and not so much as to photosynthesize.

During the rooting time, remember to keep your temps in the mid 70s, and RH around 90%. If you see the RH is dropping or the cuts are wilting, check the medium and if it's dry, give her a good dip about half way up the pellet in plain water.

Besides all that, time is a factor in any of this cultivation stuff we're into. Just remember it takes time to do anything and to be patient. However, if you're impatient like me, you might try another method... (continued in next post because this is insanely long-winded and must take a break)
