From that description, I have no idea exactly what you are attempting to do. "Clear"? Please describe exactly what you wish to accomplish.
BTW -- you say it takes too long to load...as in boot up fresh from a batt pull? How long is too long? And when did this start? If it started after one app was installed, they you already know the reason. Typically, 20 minutes to be fully usable (not just rebooted, but truly fully usable without lagging) is, in my experience, not uncommon.
Occam's Razor nearly always applies when troubleshooting technology issues!
