postfix slow start - should I disable it?

compress=“cat” reduced kernel initialization time… but somehow NetworkManager-wait-online completes way before there’s connectivity (I have a service depending on network-online.target), this happened for 50% of the boots since I made the change to initrd. Never saw that before.
