This is often/sometimes referred to as ASIO Load, so it's a nomenclature issue. CbB does have a reputation for poor performance (in terms of number of plugins that can be run at a given latency) and whilst some of this is down to not measuring like with like, it needs its game to be upped in order to be seen to be competitive (some kind of hybrid audio engine, which separates non-input monitored tracks to be handled with greater latency and hence better performance than monitored tracks, and which is present in some way in all(?) non-live focused commercial DAW is de rigeur now really - probably my number one missing feature to make it competitive*).
* Yes, more than a built-in sampler which can be worked around to some extent - core engine gaps can't be.
