How much energy is needed to turn on NPN transistor?

So you want to charge 35nC in way less than 5ns? That would need current of more than 7A from your gate driver, but preferably much more to get the turn on time short.
I don´t thing such a big mosfet is suitable to be run at 10MHz.
 
What gate resistor do you have? More than 2.2 ohms?
