Are you running any themes? It could be that. When I had a theme running I would get the little black busy clock all the time and it drove me nuts! Now I am running the default theme and my Storm is pretty fast. My file free memory is holding at a whopping 15megs and it is still pretty fast. Let me see what happens when I wipe my memory... after wiping I got 2megs back, so I am at 17MB free. But I also have a ton of apps on my phone and it is still running nicely. May delete a few to free up memory. I am not using a few of them.
