I alway "master" during my mixes so i'm using CPU hogging Native plugins like Ozone, T-Racks and lots of UAD. Anyways, on my HDX2 system, i've found that when I stack a bunch of plugins on a single master aux, it kills my CPU. However, if i cascade multiple auxes and place just one or two plugins on each aux, the CPU usage and 9073 errors reduce dramatically. It was a revelation when I found this solution. Logically it doesn't make a lot of sense to me, as its the same amount of processing, but for some reason it seems to share the load better across my CPUs. These days I'm using 4 auxiliaries at the end of my mixes. I don't get a lot of 9073 errors and my sessions are quite massive, often with the CPU floating around 90%.

It's because one track can only use one CPU core, so when you spread the plugins over several tracks you basically spread the load between different CPU cores.
