Try clearing the log - press and hold "alt" button, while keeping the "alt" button pressed press "lglg" and a log window will pop up. Hit the BlackBerry (menu) button and select clear log, confirm the deletion. Now do a battery pull.
Hopefully, it will make your BlackBerry fast. Report back if the problem continues so someone more experienced can help you.
