Faster courts benefits Nole. He will hit more aces and have less long rallies to conserve more energy.
Novak Djokovic is the last player who needs any sort of advantage at Rod Laver Arena, where he has been dominant, but it looks as if the increased speed of this year's courts might be offering him an unexpected one.

AO 2021:
"This year at the Australian Open, courtesy of the extra zip and pace on the courts, Djokovic's service numbers have skyrocketed. Through his six matches en route to the final, he has sent down 100 aces, considerably more than anyone else in the tournament. Only two others managed to reach 80,
Alexander Zverev (86) and
Milos Raonic (82). Unless Medvedev sets a new record for aces in a Grand Slam final, Djokovic will finish the tournament on top of the aces leaderboard, the first time he has ever managed the feat at a major. The extra aces and cheap points he's winning are coming courtesy of the court's lack of grip, which is shaving less speed off the ball and allowing it to skid faster."
Djokovic is not troubled by fast courts, that's why he won 7 Wimbledon titles, 6 Indoor Paris Masters and 6 YEC. Other player like Nadal is more troubled by fast courts and that's why he hasn't won YEC nor Paris Masters and has more big titles on Clay courts.
