Agreed. In-process is where you get things like instruction-level parallelism. I think our university programs have failed us the most in this regard. ILP should be drilled into every student's brain as the penultimate performance hack. Once you start separating everything into a bunch of different buckets/systems/processes, none of these advantages can be explored anymore. In some cases, ILP can give you a 100x improvement in performance. That's serial throughput. This is the reason many developers consider bit manipulation/hacking to be essentially free.
