He’s probably referring to the tendency of non-flow-isolating AQMs to drop packets indiscriminately when under load.

Cake is flow-isolating and thus applies a separate AQM algorithm to each flow.  As such, UDP gaming/VoIP traffic won’t get dropped unless it exceeds its fair share of the link, which is unlikely for a well-designed, lightweight protocol.

We really should make an effort to put a more intuitive GUI interface on this.  These questions indicate a user overwhelmed by many options without guidance.
