BTW, this dvdt, parasitic effects are more prominent in large fets. I believe the ideal approach was to slow down the initial Gate drive current until Vgs has reached the miller plateau, by which time Vdrain-source has aceived a lot of its transition, then speed up the drive current so as to achieve low Rds. Slowing down the transition solves the dvdt problem but when multiple parallel mosfets are involved we are possibly getting into Spirito Effect territory, forward biased, linear region driving large currents.
