@roanutil @mattiem @mattcomi You must be doing ObjC projects then. I'm mostly doing Swift and that usually is bound to a single CPU. It can scale out if you have a lot of independent modules, but that seems rare.
As mentioned the one occasion I see system load is if swift-nio-ssl is being built for the millionths time (it's C++, so it actually runs parallel). BTW that there is no binary support in SPM is just a ridiculous waste of time and resources.
