Practice is the key here, i find playing scales all across the fretboard slowly and then fast real helps improve picking speed. Also playing a lot of cof, darkthrone, iron maiden etc. Oh yea, i just remembered, when i first started playin all i ever did was crack out Angel of death by slayer and try to keep playing it for half an hour. After a while your speed increases shit loads. But your hands go completely dead at the end
