task killer does not improve performance. Maybe it does in short timespan, but long term it doesnt. You'll see alot of task open in teh task killer.. you thought why the heck its there.. its taking my mem. sO you kill it. A few min later its back up. Its the BG process. dont kill it. let it finish its task. If you kill it, it will only come back up again n REDO the whole task it was doing ealier. Result? SLOW phone tht everyone is complaining.

This applies especially to the galaxy S! I uninstalled all task killer n my phone is flying w/o a single hitch.
