My RAZR HD was getting slower and slower in response, which I found very annoying. I figured it was using alternative launchers and too many apps installed and I'd have to live with it. Or I thought it was only having 1 GB of RAM, but research on the 'Net shows that Android should still be OK with a full memory, it'll just swap stuff in and out.
So anyways, this is about cleaning your cache in two places: app caches and the cache partition. The first one can be done with any cache clearing app from the Play Store. I installed App Cache Cleaner (Pro) for clearing app caches (equivalent to going to Settings > Apps > All Apps and clicking each app in turn and clearing the cache), but honestly it didn't seem to do much to improve speed.
So I just did the second thing tonight: wiping the cache partition, described here:
Wow. The phone is responding instantaneously. Wow. SERIOUS improvement in response.
I followed these instructions EXACTLY as they say, I have reproduced here:

To add to that, I have read several posts saying you should repeat Step 6 3-4 times. After that, I usually press and hold the Power Button and Volume down button for 8-10 seconds (until phone restarts). Also a good idea to power your phone down at least once a day (Motorola recommendation).

You won't lose any data or configurations by wiping the cache partition, and you certainly won't lose any configuration by powering the phone down daily. Just make sure that anything you're doing before you power it down, you're done with, or is saved.

I didn't erase the original instruction in my original post but since the Kit Kat update, the keystrokes from the triage screen (the 'dead' Android) weren't working so I fiddled and got it to work since Kit Kat by doing this:
Step 5: From the Droid Triage screen, press and hold the middle of the volume button and then press and release the power button. The blue menu appears. Volume down to select Wipe Cache Partition and Power Button to select.
