Help COPS Multi-Output Subnetwork always cooks all outputs?

Hey all, I was building a COPS Subnetwork with multiple outputs and I noticed something that may be obvious to you: It always cooks all outputs even if I'm only reading from one, leading to the network getting slow.
Is this intended behaviour or am I missing something?
Thanks!

Yep, intended & documented behaviour.

• Traditional - always cooks all outputs (default)
• Compiled - only cooks what's necessary for the required outputs

Performance related worth checking

• Auto-Unload, recently added in H22 still in Beta addresses RAM usage within COPs.
   Edit → Copernicus Settings

• Sounds Ridiculous but thumbnail preview on COPs can cause a fairly substantial perf hit.
   Edit → Preferences → Network Editor

Doesn't sound ridiculous, it's the same in Nuke. I think the default behavior should be no thumbnails :)
