How much time is between the waves? And is there any real disadvantage to this as opposed to them all being simultaneous?
The salvos occur 0.5 seconds apart. Firing an LRM10 through a 6 tube hardpoint would result in a salvo of 6 and 0.5 seconds later a salvo of 4.
The topic of Lurming (LRM Boating) is skull crushingly complicated.
To answer your specific question, it is both an advantage and disadvantage.
In an ideal setting you want to launch as many missiles as possible with smaller salvo sizes. This reduces AMS kills, reduces the time your target has to dodge, and delivers as much damage as possible to the targets middle i.e. the Center Torso.
