Did you ever find an answer to this? I'm stuck on this query too. I found that increasing many tuning parameters to their recommended values made performance on the steps prior to this workable, but this one is just impossible to run.
My resources: VMWare Workstation Player, 8 cores, 56GB RAM, NVMe SSD storage, real hardware is 2x8 core Sandy Bridge Xeon processors. I can't imagine what people trying to run on the default configuration are seeing, that was completely unusable and unstable.
