24 connections RAW_BUF_SIZE 524288 3.5 hours

However one observation that I am going to (try) to test is that we are
spending a lot of time waiting for the last thread to finish. I
wouldn't be surprised if I could cut the time in half if I could script
this out to do:

table.data->table.pk->table.index
table.data->table.pk->table.index
table.data->table.pk->table.index
table.data->table.pk->table.index
constraints

versus

table.data
table.data
table.data
table.pk
table.pk
table.pk
table.index

...
