Yep and the bottleneck moves around as well, Intellij used to take an age to do a full index rebuild on large multi-language projects, on the Ryzen 1700 I have it pegs all the cores at 100% for a few seconds and is done, the bottleneck now seems to be back on the disk access. I pigz'd a 5GB archive in <20s and the bottleneck there was the SSD again, (Samsung evo 850 but it was a lot of small files and ~60,000 PDF's (don't ask...)). The Ryzen 1700 paired with a good SSD is a dream for development workloads.
