I need help til improve my speed when playing. Please share your own practice techniques... And if possible, write me a tab with something I can practice with my meteronome...

Thx in advance
chromatic scales etc 1 2 3 4 but i cant stress enough how you shouldnt focus on improving your speed. its not speed, its the coordination between your right and left hands. try splitting your notes into groups of 3, i found that helped me leap forward in my speed a lot. but just enjoy it, technique, dynamics, all what you should be focussing on before speed.
d----12-13-15------------15-13 and repeat
____d ^ d ^ d ^ d ^
d=downward pick
^= upward pick

alternate picking = speed imo

the trick is to master that 4th upward pick when going on to the 'new' underlaying string
