For example, recently released IK Multimedia T Racks Tape Machine collection. One instance of the plugin takes about 15% of one core. In a large project this is a lot and you need to think where to use it or use freezing. Then you have a suite of plugins by Acustica that use a variant of dynamic convolution (volterra kernels) to simulate equalizers, compressors or reverbs. Virtual synthesizers like Diva in pristine mode and enabled multi core can also take a lot of resources. You really need to budget what to use where so that it won't break up - which is a skill in itself, that hopefully in the future won't be relevant as much.

I totally agree with this. I can't stand having a resource limit on creativity when I'm making music. What's worse, is even if you get dedicated hardware (DSP chips, etc.) they are normally designed for specific software, and aren't (and likely can't be) a 'global accelerator' for all audio plugins, regardless of the developer.
