Root Why has my phone gotten so slow?

[sega dude]

My Triumph has gotten very slow. There is like a 5 second delay when I touch an app to when it actually launches the app. A black screen usually shows up before the app's title bar does. It lags when I unlock (I'm using the Holo style ring lock). Wi-Fi turns on slow. The phone is just overall sluggish. Is it because I didn't do factory resets before flashing updated ROMs? I have never done this. I usually wipe the cache before I flash an updated ROM but I forgot the last two times. I've updated CM7 to CM7, I've never used a CM9 ROM. Running Fast Reboot used to help, but it doesn't really anymore. How can I make the phone less slow without doing a factory reset?

Well we normally recomend starting fresh. We know it's a hasle, but it's not required to flash a new ROM every time we make a release. Some of the changes require it and some won't. And we don't flash over from one build to the next so we don't know which will need it.
