Nope. The 'activation' of the Guanyin is faster than the sound.

But the attack is not, that's a normal -well, not so normal- high speed attack. That's why Meruem states that the 'pray' is a redundant movement, since it takes time that could cost your life, but that's the only moment Netero outspeeds him and is able to attack during the whole fight. Like, those faster than sound movements are limited, he can't move at that speed forever, we see this even on his youth, when he was even stronger, that he used to prepare, pray, then, punch, and a faster than sound attack was the result of this process. For the Guanyin Boddhisitiva Ability, the preparation isn't needed anymore, the pray is faster than sound, and the attack is a high but "normal" speed attack.

If each and all of Netero's movements were faster than sound, the King wouldn't even have time to land on the ground after a hit, Netero would have played with him as much as he wanted.

We should mention that the Hands ARE really fast, they can hit Meruem without problem no matter how he counters until he finds a "flaw" to disrupt Netero's tactic.
