Using a theorem of J. Groves we give a ping-pong proof of Osin's uniform exponential growth for solvable groups.We discuss slow exponential growth and show that this phenomenon disappears as one passes to a finite index subgroup.Finally we make a connection between slow growth and the Lehmer conjecture.
