Haven't thought about that. Thanks, useful! BTW if you haven't perform clearing of the non-volatile memory that will also help:
Speedometer - > Developer Info -> Non-Volatile -> Clear Non-Volatile

And as lolypop000 wrote deleting the mlg_history.db will also help. I know that this file is also causing sound/bluetooth problems. It seems that this file gets corrupted some times.

Cheers,
