Erlang VM is actually design around full CPU utilization. It will typically spin up a thread for each core and schedule processes (Erlang not system) across them. It's actually because it's designed to not share memory that it excels at parallelism!

This design does not do well at CPU parallelism for many workloads. Consider texture sampling in rasterization, to name just one example, in which shared memory is extremely important to get good performance.
