I second scaling the up-front init with the zone size. The 7TB system I
was booting has only 32GB per NUMA node, which at 1GB per 0.25TB would
work out at 128MB up-front init per-NUMA-node, which worked nice and
booted faster yet.
Even booting with 64MB per NUMA node worked great, so there is adequate
margin for the 8 cores, just I guess we'd need to enforce a minimum of
eg 64MB or so.
Thanks,
Daniel
